I am porting a special purpose Android VNC client that works with the popular commercial Sibelius PC and Mac program. I am currently addressing the numeric keypad differences between Mac and Windows keyboards. I am sending 0xffbd (KP_Equal in keysymdef.h) but am not receiving the key event on my Mac Lion system running the 4.0 beta server. I am using http://manytricks.com/keycodes/ on the Mac to display the key clicks.
Appears to be a bug.
