Openoffice menu (font?) problem/bug
 

Hi,
In all the applications belonging to the openoffice suite, I see the following bug. The space is replaced by a squarish character. Attached is a screenshot that will show you what the problem is.

Anyone facing the same problem or can tell me how to fix it?
