[vbox-dev] Resizing of Windows guest not working in SVN Build =>r39104

[Perry Halbert]

More testing shows this not to be guest addition related.  It appears to 
be host side as far as I can tell and affects Windows guests only.  If 
the guest is set to a size before you update there is no issue it starts 
at the size stored in the .vbox file.  If however you try to resize the 
guest down and back up with the mouse drag it will decrease but it can 
not be increased.

As you can see this is indicating the size change, however the frame 
does grow but the guest does not.  This is an XP-x86_64 guest.
