Is anyone having or has anyone had problems in SW 2010 x64 running on Windows 7?

Here's a couple of problems I've been noticing since my switch (two weeks ago):

• Popup dialog boxes often come up behind the SW window, so if I don't notice the icon in the task bar, I'll think it's frozen!
  
• I've been losing the view orierntation dialog box (although I found a utility from another thread that works great at getting it back)
  
• Parts are being hidden automatically in some assemblies (sporadically, I can't find a pattern)
  
• Some mates are giving weird errors.  For example, I'll have a mate that used to work on the 32bit version of SW2010, but now it gives an error.  When I go and try to fix it, it'll tell me that some of the components are supressed (which is a particularly odd message seems as how I'm clicking the face of the component to try and correct the mate!).
  

I've got the latest SW approved video driver for the nVidia Quadro 3800 that I'm running.  I'm running the latest SP for 2010.  I'm hoping there's someone out there that can tell me if I'm doing something wrong!!!

By the way, other than the problems in SW, I'm really enjoying Windows 7.

Thanks in advance for your comments.
