The latest build (2217) has locked up for me a couple times in Windows. Once while opening a file from the GoToAnything panel (the lockup froze a progress bar in the text view), and the second time with the panel open, searching for a different file.
This is a relatively large project (~10k files), but previous versions of ST2 handled it fine. None of the files themselves are particularly large. Is there anywhere I can check for debug/crash information?
