However, I can't get OpenGL to work. I've traced the problem to sqMacOpenGL.c. The call to <FONT class="Apple-style-span" face="Monaco" size="2"><SPAN class="Apple-style-span" style="font-size: 10px;">GetWindowGreatestAreaDevice()</SPAN></FONT> fails with an error code of -5600 ("Invalid Window Pointer"). I assume that this is because <FONT class="Apple-style-span" face="Monaco" size="2"><SPAN class="Apple-style-span" style="font-size: 10px;">getSTWindow()</SPAN></FONT> doesn't work when Squeak is running in a browser plugin.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I hacked it by avoiding all the GDH stuff if we are in a browser, like so:</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV style="margin-top: 0px;
