NEW: Macro KB shortcut doesn't work (otherwise Ok)
 

I'm using Excel2003 (SP2) and both previously created and new KB shortcuts
for different macros, don't work. The macros otherwise are running fine
(Tools-...)

Now, I'm aware of all previous discussions on this issue here, but none of
the answers or suggested solution work for me. I've tried many different
CTRL+<key combinations, I'm not using [SHIFT], I haven't got the same key
assigned to different macros... the works. They still won't fire off.

Anyone?
