ArcGIS 10 problem with IGxDialog

Has anyone had the opportunity of updating an AO project from 9.2 to 10.0 and had issues with the IGxDialog object? I get a
“ vshost.exe has stopped working” error every time I hit the following line

Dim pGxdialog As IGxDialog = New GxDialogClass()
Dim mdbFilter As IGxObjectFilter = New GxFilterPGDBFeatureClasses
pGxdialog.Title = "Pick the feature class you want to use"
Dim pEnumGx As IEnumGxObject
pGxdialog.ObjectFilter = mdbFilter
pGxdialog.StartingLocation = "c:\"
If Not pGxdialog.DoModalOpen(0, pEnumGx) Then <--ERROR HERE
Return
End If


This could also have something to do with Windows 7, because it caused other minor issues also.

FYI, I already disabled the VS Hosting process in the project debugger and deleted the vshost.exe in the bin folder, which should’ve fixed it, but didn’t

thanks
