Both QUERY ANALYZER and the VB IDE can lock up if you are running some kind of loop or encounter an odd bug in your code.

I've lost both .SQL files and VB changes due to this.

I hate it - there should be an option to "save before every run" - I've found that option in other applications - like video editing software and other graphical tools.

I voted for 5-10 - but I'm sure it's been more than 10 in the past few decades!
