--- Comment #2 from noabody@yahoo.com --- Steps to reproduce: Delete .wine, run winecfg, wine 7z1900-x64.exe, run 7zFM.exe, double-click computer, double-click "Z:", crash dialog appears that states "Unknown error"
Can be bypassed by setting the registry to existing "Z" location
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\7-Zip\FM] "PanelPath0"="Z:\home\"
