--- Comment #2 from Rosanne DiMesio dimesio@earthlink.net 2010-06-01 20:15:51 --- In wine-1.2-rc2-91-g4ae5325, I'm no longer seeing a crash from this, with or without an override for riched20.
Without an override for riched20, the Visual Basic Editor now throws up an error message that says "System Error &H80040110" when you try to insert a UserForm. Setting an override for riched20 fixes it.
