http://members.optusnet.com.au/madonion87/Release.zip

someone already suggested that it might be the compiler optimization problem, i tried turning off optimization in MS VS.net 2003 but it doesnt help

any ideas would be very appreciated

this might help

"in the release build, after GetMessage is called, it goes on comparing whether the call has failed, and if not calls TranslateMessage and so on but the loop is very tight. whats more odd is the program never seems to pass control to windows, and forever looping and handling messages.

whereas in the debug build, after all messages are handled, program passes control to windows after a GetMessage call."

another guy i know in ocau forum said it, i'm not very sure what he means though

You need to post source code (some code fragments may be posted here, or make the whole project available for download). exe file doesn't help us to solve your problem.
Except of this, I don't beleive there is an expert who downloads unknown exe file from WEB and runs it on his own computer :-)

Everything that you do not post here is pointless, as it renders the Q worthless for others. Sorry.

for some good discussion on why things work in debug and not in release, and what to do to fix it.

So, have you also tried to _DEBUG_ your release build then?
