Thread: RMB Context Menu

Aloha,

I'm having a devil of a time trying to do a simple RMB context menu - and I'm sure I'm misunderstanding something basic. Although the menu displays on RMB - the lowest menu item's text doesn't display - I just get vertical bars. But the 2nd level menu displays fine when hovering over the associated parent menu's vertical bar. A jpg of the situation is attached in case I'm not explaining myself clearly.

In case it makes a difference - I'm using Windows Vista Home premium (32 bit).
Compiled using Visual C++ 2008 Express

Thanks in advance for any help in solving this problem.

Aloha

Thanks novacain,

BTW, the non-display problem I was having was caused by using

hMenu = CreateMenu();
instead of
hMenu = CreatePopupMenu();
