Update: 27 Dec 2007 10:39
I just tried running the program is safe mode. The program runs flawlessly
if I am logged in as 'administrator' but not when I am logged in as myself -
and I am the administrator.
Looking in the task manager, all the processes running are the exact same
weather logged in as administrator or as myself, but I get the same error
when I try to run it as myself either in safe mode or normal mode.
Also, one other thing - the window is square and rather small with a black
section at the bottom when logged in as myself, and normal size, rectangular,
when logged in as admin. when it works right - both in safe mode
