--- Comment #2 from Jacek Caban jacek@codeweavers.com 2011-11-22 15:08:07 CST --- There are two things:
- When upgrading we intentionally keep the old installation. Uninstalling is not worth the trouble to do by default, but it should be harmless to remove old Gecko installation.
- Explicit uninstall of Gecko package should remove its files. I've just tested and only 1.4/wine_gecko/windbgdlg.exe remained installed for me.
