Summary: Microsoft Office's Excel installs, loads but can't open
                    files
           Product: Wine
           Version: 0.9.7.
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: wine-files
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Defining winver=win95 in winecfg for installer and excel.exe, I managed to
install Microsoft Office SR-1's Excel (custom install, Excel alone). It
installs, loads, and runs without crashing (and no warning whatsoever). I
updated it to SR-2, no problem.

However, trying to open a file leads to me being unable to navigate drives! The
best I can do is move downwards from drive_c (I can't move backwards).

I'm using WineHQ's binary RPM for Mandriva on Mandriva 2006 Community x86-64.

I only get a load of stubs when I do so:
fixme:richedit:RichEditANSIWndProc EM_SETTEXTMODE: stub
fixme:richedit:RichEditANSIWndProc EM_SETFONT: stub
fixme:richedit:RichEditANSIWndProc EM_LIMITTEXT: stub
fixme:richedit:RichEditANSIWndProc EM_SETTEXTMODE: stub
fixme:richedit:RichEditANSIWndProc EM_SETFONT: stub
fixme:richedit:RichEditANSIWndProc EM_LIMITTEXT: stub
fixme:richedit:RichEditANSIWndProc EM_SETTEXTMODE: stub
fixme:richedit:RichEditANSIWndProc EM_SETFONT: stub
fixme:richedit:RichEditANSIWndProc EM_LIMITTEXT: stub
fixme:richedit:RichEditANSIWndProc EM_LIMITTEXT: stub

It looks like a character type mismatch as I get several white squares following
drive letters, and the File name input box gets a scrollbar.
