Thanks for the advice and info everybody. I've made some further progress
on this. A user at my company has pointed out that the same problem
occurs with the menus in 'nedit' and since the main point in common
between nedit and maya 2010 is that they both use the motif toolkit I'm
suspecting this is a bug in the motif libraries. Since nedit is open
source I can try attacking the problem directly there and then hopefully
advise autodesk / or hack our maya install to use different/patched motif
libs once I isolate the root cause.
