Why is my MsgHook always called twice with apparently the same messages ? (WN_KEYDOWN, WM_CHAR and probably all others as well) I get this problem under 3.11, Win95, and WinNT. I am using a 16-bit DLL from Authorware in case it matters. I am sure I have only installed the MsgHook once. I install it by: hMyHook = SetWindowsHook( WH_GETMESSAGE, gHProc ); where gHProc is the result of a MakeProcInstance(); -- Win95 - Where do you want to go today ? Well, not to a 2 year late OS Only DOS is worse than Win95.

I have to look at the wParam, and only react when it is PM_REMOVE -- Win95 - Where do you want to go today ? Well, not to a 2 year late OS Only DOS is worse than Win95.
