Arduino 1.0.5 and Win7

The new version seems to be really sluggish when accessing the menus. Is this a normal occourance, or an issue with my machine?

update: The symptoms only occour in windows7, but not in an instance of WindowsXP running on an VMLite VM on the same PC.

I have desktop with Windows 7-64bit Professional and am using 1.05 IED. Things work great.
