[platform-swt-dev] MenuItem's not generating ArmEvents

[Fred Potter <fpotter@xxxxxxxxxxxxxxxxx>]

On Windows CE, MenuItem's don't seem to generate ArmEvents when they are 
clicked.  I've tested this against the XP release as well, and it works 
fine there.  This bug seems to be only on CE.

You can check this bug using the very same code from one of SWT snippets.  
I have attached that same code here for your convenience.  

Do you think this might be a platform limitation, or a genuine bug?

This bug was tested using the 3.1M1 release, but was also present in 3.0.
