Here is a small annoyance that I have with TextMate. When I want to open a new file in TextMate when it's not running it also opens the last opened file. Now for some cases that's just nice of him to do but in most cases I end-up closing the previous file. Maybe this is a simple setup/preference issue? Any ideas?
It's not something you can set in the app preferences.
If you want to change this behavior, open Terminal.app and type
This will make Textmate not remember the last session.
