Followed the instructions in: http://wiki.winehq.org/RegressionTesting Installed and configured git Compiled Wine Backed-up my old wine directory Installed Homesite ran: git bisect start git bisect good wine-1.2-rc6 git bisect bad wine-1.2-rc7 What now? Am I supposed to recompile again? This is where I'm lost and the instructions are not clear at this point. The other problem I have is that this is the computer I use to make a living. I normally wouldn't run unstable code, but the stable version makes using Homesite very difficult. The unstable version fixed almost all of the problems I've had until now. Is it possible to run dual versions? So I can use rc6 for my day job, and test with another?
