Operating Systems Requirements
The Topologi Mentor for PureView™ is intended
for use with Windows NT 4.0 with Service Pack 5, ME,
2000 Professional, 2000 Server, 2000 Advanced Server,
or XP operating systems running on Intel hardware.
For more exact details on RAM requirements, see the
The Topologi Mentor for PureView™ is intended
to run on 15" or greater monitors for desktop systems,
and at resolutions of 640x480 or greater pixels, and
with 16 colors or more.
The editor dedicates as much screen real-estate as
possible to the text being edited. Consequently we recommend
a larger monitor rather than a smaller one, but for
reasons of general user efficiency rather than as a
particular requirement of this product.
A Pentium 400MHz or faster processor with at least 196 megabytes
of physical RAM is preferred. Running with less memory may
cause disk swapping which has a severe effect on performance.
If you are opening many documents or large documents, or have
several applications open at the same time, more RAM is appropriate.
Similarly, a generous setting for the system's virtual memory
may be appropriate.
If you are running Windows XP and also will be using other
applications open at the same time as the editor, you should
consider having more than 256 Meg RAM. See CNET article When 64MB isn't enough for XP, noting "XP requires
as much as 256MB to really cruise." We recommend a swapfile
size of at least 256 megabytes.
You should have 50 megabytes of free disk space before attempting
to install the Topologi Professional Edition on Windows,
which includes a complete Java 2 Runtime Environment 1.4.2.
Support for wheeled mouses is expected in a subsequent release.
XKeys Foot Pedal
Foot pedals such as the Xkeys pedal may be used. Suitable
mappings when the Sidebar is not used would be ESC (main pedal),
ctrl-. (right pedal) and ctrl-, (left pedal). Suitable mappings
for when the sidebar is commonly used would be Ctrl-Enter
(main pedal), ctrl-DownArrow (right pedal), Ctrl-UpArrow (left

Java Version Issues
The editor has been tested and developed for JRE 1.4.2.
The PC version comes bundled with a JRE 1.4.2. We recommend
using JRE 1.4.2 for Windows, Sun JRE 1.4.2 or IBM JRE
1.4.2 under Linux. For Mac, we have tested using JRE
The editor uses the fonts installed on the current
computer. Consequently, rare characters may not be displayed
The editor uses Unicode to represent characters, and
supports a wide range of encodings for import and export.
The editor is intended to support any character in Unicode
which is represented by a single code point in UCS-2.
However, characters formed from combining character
sequences (e.g. Thai) will usually edit and draw correctly,
from version 1.3.1_6 of the Java JRE. Note that data
imported, pasted or entered using the Keyboard menu
will be normalized into a single code point, if such
a code exists.
The editor is intended to support left-to-right languages.
However, on certain systems (such as many Windows systems)
the display system will correctly transpose characters in
right-to-left scripts. These will display correctly (within
each text fragment) however, the caret is not aware of right-to-left
order and so may be frustrating to use.
The editor is intended to support scripts whose normalized
Unicode format does not make use of combining characters.
Please note that combining characters will be preserved in
the editor and be entered or detected by using the Character
Code field in the bottom right of the editor. On certain systems,
the display system may correctly draw the combined characters
to screen, however, the caret is not aware of combining characters
and so may be frustrating to use.
If your operating system has not been recently installed,
we recommend updating your fonts. Microsoft provided free
updates to certain standard fonts to include more characters
and Unicode mapping tables in the fonts. Microsoft withdrew
their distribution, but apparently their licensing allows
distribution from other sites. In your web browser, search
for Core Fonts Sourceforge and download and install
the fonts Courier New, Times New Roman, Arial, etc.
From http://www.microsoft.com/typography, we also draw your
attention to the Font Properties Extension which lets you
examine fonts in your system in more detail. This is not needed
in connection with the editor, but can be of general use for
resolving font-related typesetting issues.
We also recommend that you install from your system installation
disk the Accessory Keyboard Map, which lets you see all the
characters ("glyphs") made available in each font.
You can use this to cut and paste into the Topologi Professional Edition.
In Windows 98 only, version 1.1 of the editor has a problem
displaying characters that are not in the current locale of
the editor. We recommend you only edit using ASCII characters
and use character entities or references for other characters,
at this time. Also, certain fonts with inaccurate font metrics
may cause memory problems, experienced as slowness.
