Hi,
We have a VSTO 4.0 Add-in for Excel 2007 that seems to have issues with Memory leaks, but only certain documents and only on Windows 7. The behavior is similar to the LCID proxy issue that was supposedly remedied in VSTO 4. The memory spikes at about 1.2 to 1.5 GB then throws an OutOfMemory Exception. This only seems to happen when I try to open certain documents when runing on Windows 7. If I open the same documents in XP, the memory certain goes high but I do not get an exception. Basically, I get various exceptions and never in the same place twice:

Here's another one:
----- Source: System.Windows.Forms -----
System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

at System.Windows.Forms.Control.PreProcessControlMessageInternal(Control target, Message& msg)
at System.Windows.Forms.Application.ThreadContext.PreTranslateMessage(MSG& msg)
When I save the documents as stand alone docs and do not open them using the VSTO Add-in, it is able to open them with minimal memory. When I use the add in to open them, that's when things spin up and crash.
Any help or pointers as to why Windows 7 has these issues would be much appreciated.
Thanks,
Erick
