This problem presence only in 5.81 and 5.82 versions of BCGControlBar. Version 5.8 CBCGMenuButton works right.
SYMPTOMS
1. Launch the BCGControls Example (release version); 2. Activate the menu button in right top corner of "BCGControls Example" dialog. Popup menu will appear; 3. Click any other controls, like color button, standard button, standard comboboxes (except slider, BCGButton, CBCGUrlLinkButton and checkboxes) inside the dialog window WITHOUT closing the popup menu. So, just click the "OK" button; 4. Application completely "frozen". No message processing. User cann't close the window and overflow by fury.
1. Application freezes. Bringing up Task Manager in Win2k one can see that the CPU is up to 100% which in most is an infinite loop problem. Sometimes after about a minute the infinite loop will break and the application is back on track. Also, sometimes the End Process button will free CPU resources.
Anyway it looks to be a seriuos problem with the CBCGMenuButton.
Many thanks for the bug report! To solve the problem, please make the following change in the library source code (we'll add this fix into the source code too):
File BCGContextMenuManager.cpp
[246] while (::PeekMessage (&msg, NULL, 0, 0, PM_REMOVE)) [247] { [248] if (!::IsWindow (hwndMenu)) // ADD THESE 4 lines [249] { [250] break; [251] }
Gorgeous bug in CBCGMenuButton!
