<h2> Swap Files
</h2>
</a><a name="491999">
<p>When working with large model files, Visual Modeler runs faster
with a permanent swap file. You can set this from the Windows
Control Panel. If Visual Modeler reports "low memory" during normal
operation, increase the size of permanent virtual memory.
</p>
</a><a name="492000">
<h2> Video Cards and Drivers
</h2>
</a><a name="492001">
<p>Visual Modeler was tested with a number of video cards and drivers.
The Diamond Viper Pro Video card
required the driver be updated to driver 3.5 v1.2 on Windows
NT. If you experience display problems with other video card
and driver combinations, check with the video card vendor to
see if an updated driver is available that may correct the
problem.
</p>
</a><a name="492002">
<p>Visual Modeler uses the current font size, among other factors, to
determine the optimal size of a class icon when autosizing it. If
your video driver supports large and small fonts, you may
notice that a class that was autosized and saved with small
fonts does not appear autosized correctly when read in using
large fonts, and vice-versa. You can correct this by either:
</p>
</a><ul><a name="492003">
<li>Choosing <kbd><b>Tools</b></kbd> &gt; <kbd><b>Autosize All</b></kbd> to resize all icons on a diagram
</a><a name="492004">
<li>Toggling <kbd><b>Edit</b></kbd> &gt; <kbd><b>Diagram Object Properties</b></kbd> &gt; <kbd><b>Automatic Resize</b></kbd> off and back on to
autosize selected icons
</a></ul><a name="492005">
<h2> Printers and Printer Drivers
</h2>
</a></ul><a name="492015">
<p>If you experience printing problems with other printer and
driver combinations, check with the printer vendor to see if an
updated driver is available that may correct the problem.
</p>
</a><a name="492016">
<h2> Windows 95 Mouse Driver
</h2>
</a><a name="492017">
<p>The <code><b>EM_EXEC.exe</b></code> mouse driver file on some
Windows 95 PCs-especially laptops-that interferes with
Visual Modeler. (The typical symptom is a crash while you are
entering a class name directly on a class diagram, but Visual Modeler
may also crash at other times with varying frequency.)
</p>
</a><a name="492018">
<p>This mouse driver file must be deleted or renamed for Visual Modeler to
function properly:
</p>
</a><ol>
<a name="492019">
<li>Start your PC in command prompt mode. (Press <kbd><b>F5</b></kbd> during
boot and select command prompt start.)
</a><a name="492020">
<li>Go to the <code><b>C:\mouse\system</b></code> directory.
</a><a name="492021">
<li>Delete or rename the file <code><b>EM_EXEC.exe</b></code>. This should <em>not</em>
impact any Windows 95 performance.
</a><a name="492022">
<li>Do a normal reboot.
</a></ol>
</p>
</a><a name="492023">
<p>To install a newer version of the driver, which does not interfere
with Visual Modeler:
</p>
</a><ol>
<a name="492024">
<li>Contact Logitech to get an update. The update can be found
at <CODE><B>ftp://ftp.logitech.com/TechSupport/MOUSE</B></CODE>.
The name of the file is <CODE><B>mw7aol.exe</B></CODE>,
May 3, 1996 101k.
</a><a name="492025">
<li>When you execute that file, it will be expanded into several
other files, including a later version of <CODE><B>EM_EXEC.exe</B></CODE>
which should work together with Visual Modeler.
</a></ol>
<P>
Another mouse product that may interfere with Visual Modeler is
the Microsoft IntelliMouse, which comes with a mouse driver called
<CODE><B>Point32.exe</B></CODE>.
To solve this problem, bring up the task list in Windows and end
the task called &quot;point32&quot;.</P>
