The acrobat control is on a dedicated form. The interop assemblies for it
never even get loaded unless the form is displayed (I subscribe to the
AssemblyLoad event and log when all referenced assemblies are loaded). This
PDF viewer form is actually in a restricted part of the application,
inaccessible to the current users, so I am pretty certain the PDF control is
not related to this crash.

I will take a look at Purify though and see what it can do for me.
