Summary: VB6 IDE complains "Key is not unique in collection" on
                    startup
           Product: Wine
           Version: CVS
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: wine-ole
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Set Wine for win98, then install Visual Basic 6.
Start the IDE.  It puts up its main interface,
then pops up a dialog box "Key is not unique in collection".
This appears to be a treeview control error
(cf. http://support.microsoft.com/kb/q162523/ )
Immediately before this error box appears,
wine outputs
err:ole:ITypeInfo_fnInvoke failed to convert param 0 to VT_VARIANT|VT_BYREF from
VT_BSTR|VT_BYREF
I'll attach the relevant bits of the log.
