If you get the "Insufficient Memory" alert when you start up Spider, it is undoubtedly because your monitor is set to Thousands or Millions of colors. Spider was written before such monitors were possible. At this point you have two choices:
(1) Use the "Monitors" control panel to set your screen depth back to 256 colors, or
(2) Allocate more memory for Spider.
You will lose no performance in Spider by scaling back your screen depth, as Spider is
optimized for 8-bit color. Spider will not look any better in thousands or millions of colors. However, you may find this inconvenient if there are programs you are running alongside of Spider which prefer to have all of those colors available.
Adding memory to Spider is wasteful, because you will have to increase Spider from 800k to 1300k to support Thousands of colors. Another 500k or so should be needed to provide support for Millions of colors. All of this memory is needed to provide off-screen pixelmaps of the proper depth to support Spider's card animation. However, if you have the RAM available and want to stay in 16 or 24 bit color mode, this is the approach you will prefer.
As with all applications, the amount of memory available to Spider can be controlled by selecting the Spider application and choosing "Get Info" in the Finder's "File" menu, and then by editing the "preferred size" at the bottom of the info window.
