You can explicitly tell VB to unload dlls no longer in use with the
CoFreeUnusedLibraries Ole Api function. VB will (supposed to anyway)
do this itself periodically, but it can't hurt.
'declaration...
Public Declare Sub CoFreeUnusedLibraries Lib "ole32" ()
'usage...
CoFreeUnusedLibraries
DoEvents

Also the system will reclaim some resources when you minimize the
app's UI. Restoring it may increase usage again, but typically still
less than the previous level.
