This patch fixes the problem reported running SmartForms in bug 575
(http://bugs.codeweavers.com/show_bug.cgi?id=575). It also gets
LogicWorks running (and probably any other 16-bit app that uses the
SmartHeap memory management library).
It turns out, SmartForms does not need NotifyRegister implemented to run
(so far, at least). The problem is that when WaitMessage16 was called,
it did not yield control to the other 16-bit threads. This patch fixes
this problem in WaitMessage16.
Modified Files:
wine/dlls/user/user.exe.spec
wine/dlls/user/msg16.c
Change Log:
Separated WaitMessage16 from WaitMessage and modified it to yield
control to other 16-bit threads.
