<h2>22.1 Problems with using <small>RHIDE</small>.</h2>

<p><em><strong>Q</strong>: Why does <small>RHIDE</small> put all my source files in the
<code>C:\Windows\Desktop</code> directory?</em>

<br><p>
<p><em><strong>Q</strong>: <small>RHIDE</small> doesn't remember the path names of the files I edited
in my previous session<small>...</small>.</em>

<br><p>
<p><em><strong>Q</strong>: Why does <small>RHIDE</small> show the "Compile" option as disabled,
although there's a source file loaded?</em>

<br><p>
<p><em><strong>Q</strong>: Sometimes, especially during debugging, <small>RHIDE</small> seems to screw
up the display, or crash, or blank the screen and hang.  How can I avoid
this?</em>

<br><p>
<p><strong>A</strong>:  To prevent problems with source files not being found by
<small>RHIDE</small> or being put into strange directories, use a simple two-step
recipe:

<ul>
<li>Always start <small>RHIDE</small> from the same directory where you want your
sources to live.  On Windows, open a DOS box (you can use a shortcut to
do that), change to the directory where you want to put your files using
the <code>cd</code> command, then type <kbd>rhide <var>file</var></kbd> from the
command line, where <var>file</var> is either the name of the source file or
the name of the project file, usually with a <code>.gpr</code> extension.

<li>Use project files.  Start <small>RHIDE</small> from the directory of your project,
as described above, then add the source files to the project using the
<code>Project | Add</code> dialog from the main menu.  If you use a project
file, you can have your source files in several different directories;
in that case, start <small>RHIDE</small> from the directory where you keep the
project file. 
</ul>

<p>Alternatively, you could double-click on the project file for your
project; Windows will then invoke <small>RHIDE</small> in the directory of the
project file.  You might need to associate the <code>.gpr</code> extensions
with <small>RHIDE</small>, before you can use this feature.

<p>By default, your program's <code>.exe</code> executable file goes to the same
directory where you keep the project file, but the <code>Project</code> dialog
lets you specify a different directory, in case you need that.

<p>Display-related problems with <small>RHIDE</small> are usually caused by a faulty
video driver (on Windows 9X) or bugs in the SVGA firmware.  <small>RHIDE</small>
uses advanced VESA functions to save and restore the screen contents and
mode-specific settings, and some SVGAs and video drivers don't implement
these functions very well.  One particularly problematic SVGA card
(which will remain unnamed) has bugs even in the standard VGA modes. 
Downloading the latest video drivers from the vendor's site and
upgrading the video BIOS usually helps; if not, the only solution is to
replace the video adapter.
