I just got a notification within Textmate that a new build was available (9327), so let it update. When the new version launched, I got a second Textmate icon in the doc, which isn't entirely uncommon. However, when I quit and got back in, Textmate was not usable. When I opened a file from the Open Recent menu, no window appeared. The Window and File menus both suggested that a file was open, however. After some fiddling, switching spaces and apps, I got the window for the document to appear, but it was not functional. I could move it, but I could click the close box or edit the text. Quitting and relaunching put it back in the state where the Textmate menus looked as if a window was open, but no window appered on the screen.
I tried trashing all the com.macromates items in ~/Library/Preferences, but it had no effect. I tried trashing Textmate.app and downloading r9327 from Github, but that also had no effect on the problem. I finally downloaded r9325 from Github and that still works fine.
I am running OS X 10.7.5.
Thanks, Rob
