I was looking into my issues with menubuilder and trying to figure out ways to make the setup automatic so that everything would go where it should (since I know how to manually make wine put things in the proper place), and I noticed that no matter how wine is invoked (wine, winecfg, wineboot, winemine, notepad etc), if there is no ~/.wine it runs wineprefixcreate _first_ in order to create it.
Currently in order to fix my issues, I have to re-run wineprefixcreate after running winecfg to make sure the directories and files are put in the place I have my fake c located.
Would it be possible to make winecfg run wineprefixcreate one more time after the ok and apply buttons are pressed so that users dont have to manually run it when they use winecfg?
