Summary: It seems that I accidentally dismissed an SSL warning window from my svn repository. I was in the process of doing a project-wide search when the window popped up, and apparently my pressing return at the end of the search dismissed the window. However, there was absolutely nothing I could have done to prevent this. The window only appeared on the screen a split-second before it disappeared -- I never even got the chance to read it, I only glimpsed it. For a warning window, it should not be accepting prior keystrokes, and there should be at least a momentary pause before it starts accepting input, so that it's not inadvertently dismissed. Steps to Reproduce: 1. Launch Xcode. 2. Open a project checked out from an svn repository. 3. Command-shift-f to display the project find. 4. Type in a search term and press return. Expected Results: I don't accidentally accept an SSL warning for my SVN repository in the process of typing in a search. Actual Results: It seems that at some point during or immediately after I typed in my search, an SSL certificate warning window appeared in Xcode. I only saw the window for a split-second before it disappeared. I saw that it said something about SSL, but I had no idea what it was about. Regression: Unknown Notes: It wasn't until two days later that I saw the notice at http://sourceforge.net/community/forum/topic.php?id=4244&page#post-9502 about SourceForge changing its SSL certificates. At the time I saw the SSL warning window, I had a project open from a SourceForge svn repository, so I'm pretty certain that this was the reason for the warning in Xcode. 04-Dec-2008 10:25 AM Jeff Johnson: This may actually be an OS X bug, because it seems that modal windows in general will accept the return key before they're even fully loaded. For example, a sheet will accept a return key even while it's still dropping down into place over the window.
