Well, I just lost over an hour of work and I'd like to know what happened.
I was editing a long entry in a textarea field using the Edit in TextMate thing. The connection to the server was lost, so I did a Save As to make a local copy on my Desktop and continued working. The icon for the new file appeared on my Desktop.
After a while, TM started beeping at me whenever I saved. Fearing the something had gone wrong, I opened the file in TextEdit (it was still open in TM). Everything was there, so I quit TextEdit and went back to TM. Still getting a beep on every save, I decided to quit and relaunch TM. As soon as I quit TM, the icon for the file disappeared from the Desktop. When I relaunched TM, the file didn't even appear in the Open Recent submenu.
Any ideas? I'm running Version 1.5.1 (1070).
