I noticed someone else had a similar error/popup a few months ago. I think the important error is: err:ole:typedescvt_to_variantvt cannot convert type 24 into variant VT A popup box appears: Title: Flex List Box Control Run-time error '458': Variable usese an Automation type not supported in Visual Basic. The app uses vb6 and all dlls not included with wine appear to be installed/registered properly. The full default debug output is below: fixme:ole:CoRegisterMessageFilter stub fixme:ole:OleLoadPictureEx (0x7edf634c,458,1,{7bf80980-bf32-101a-8bbb-00aa00300cab},x=0,y=0,f=0,0x7fc9f704), partially implemented. fixme:ole:OleLoadPictureEx (0x7edf634c,458,1,{7bf80980-bf32-101a-8bbb-00aa00300cab},x=0,y=0,f=0,0x7fc9f704), partially implemented. fixme:ole:OleLoadPictureEx (0x7edf634c,458,1,{7bf80980-bf32-101a-8bbb-00aa00300cab},x=0,y=0,f=0,0x7fc9f704), partially implemented. fixme:ole:OleLoadPictureEx (0x7edf634c,458,1,{7bf80980-bf32-101a-8bbb-00aa00300cab},x=0,y=0,f=0,0x7fc9f704), partially implemented. err:ole:typedescvt_to_variantvt cannot convert type 24 into variant VT fixme:ole:OLEPictureImpl_FindConnectionPoint no connection point for {33ad4f92-6699-11cf-b70c-00aa0060d393} fixme:ole:OLEPictureImpl_FindConnectionPoint no connection point for {33ad4f92-6699-11cf-b70c-00aa0060d393} fixme:ole:OLEPictureImpl_FindConnectionPoint no connection point for {33ad4f92-6699-11cf-b70c-00aa0060d393} fixme:ole:OLEPictureImpl_FindConnectionPoint no connection point for {33ad4f92-6699-11cf-b70c-00aa0060d393}
