Hallo,
in the discussion about the needed "flying files" icon there was
mpfull.exe named as an example. I try to run it here, but get constant
crashes in THREAD_IsWin16.
What happens, as I understand it, is:
One thread (I) calls SendMessage, and in between another thread (II)
calls TerminateThread on yet another thread(III). Then the first
message tries to access structures on thread III:
