I think I may need to pass this on to you - it's blowing up during the very
initial steps.  Here's my GDB backtrace:
Program received signal SIGSEGV, Segmentation fault.

Looks like there are more than the [cosmetic] changes I made for CloseScreen().

My preliminary patch is attached, maybe you can help.
