Label issue with Windows 7

Hi Tony,

We've been using the NodeXL dlls to embed graphs within a C# application.  We're really satisfied with the API and have gotten the functionality we want out of it NodeXL.  Thanks a ton to you and the NodeXL group.  I just encountered one issue, though when I transitioned my computer from XP to Windows 7.  For some types of vertices on the graph, I had been changing the label position:

SetValue(ReservedMetadataKeys.PerVertexLabelPosition, VertexLabelPosition.TopCenter);

The position works fine on both XP and Windows 7, but on Windows 7, on vertices for which I have changed the label position, it seems that the bounding rectangle for the label (that usually turns any graph elements underneath it more transparent) seems to be off to the left of the real label text.  It seems it can vary how much it is shifted to the left, depending on the length of the label text.  Let me know the best way to get you a screen shot, if you'd like one.  

I was running the exact same code on XP with no "ghost" labels, so it appears only on Windows 7.

I haven't seen that happen before.  Please attach a screenshot here:  (You can include attachments on the Issue Tracker tab, but not the Discussions tab.)

Hey Tony,

Thanks so much for notifying me when you found the cause/solution to this issue. I'm on-again, off-again with the project I use NodeXL for, but it's great to keep getting updates and fixes from you guys. Thanks again.
