wait for more than 5 seconds on a custom combobox dropdown list control causes win32 C++ application hangs in Windows7
-
I have a win32 application in that on EditMolecule Dialog there are three tab controls.First tab control opens atom dialog. On atom dialog, there is a custom combobox control, while user clicks on the dropdownlist of this control and waits for more than 5 seconds(in Windows7),the EditMolecule window becomes nonresponsive. The same application works well in windows xp. Can anyone please suggest the solution to this problem. Thanks in advance.

Your program has a platform specific bug somewhere and you have to debug it. The info you provided is far less than what needed to find the bug. This bug can be anywhere in your program maybe it isn't gui related at all.

may be a memory leak... Try profiling your application for memory leaks use windbg to point the hangs

It may be leaky, but that (if it's the case) doesn't sound like the problem.

As always, you need to know what's going. To find out wait for the app to hang, break into it with a debugger and get you some stack traces. Do the UI thread first.

we are not able to reproduce the issue using windebug. The debugger is not breaking. Could you please suggest what can be the possible reason, because after attaching the process to debugger the issue is not reproducible.

since it is a custom combobox control, I am not getting the notification message in the wndproc.
