--- Comment #12 from Rosanne DiMesio dimesio@earthlink.net --- (In reply to Frédéric Delanoy from comment #11)
That might be because people just don't know about this (it is not mentioned in the FAQ) and just stick to one wineprefix per application.
It's not in the FAQ because no one asks about it. :-) But you are correct that the standard advice is to use separate wineprefixes.
However, explanation from comment 1 still holds. The fact one has to say "This tab is linked ..." is a sign that the UI isn't as straightforward/self-explanatory as it should be IMHO.
Sure. My point is merely that this is not something that regularly trips up ordinary users, and there are other UI bugs that do (bug 12804 comes to mind).
