I'm on my way to TI technical support, but I decided to stop in here first. There are 2 problems with my calc. the first is that sometimes, for no apparent reason, my GBDs turn into pics. they cost 767 bytes, work fine, and are still called GDBs.
The second problem is that every once in a while, when I hit prgm while in the program editor, it thinks that I'm still in the homescreen, and displays my list of prgms.
