Yes I agree with that, but the crashes I was referring to were crashes of my application being developed. Usually I get a crash and it says "You haven't declared $nnnn" or something clever like that. However, sometimes it's just so horrified at something I've done, it goes mute. Then I have to start putting in print statements and stuff. However another nice feature is, even if you haven't saved your latest change with a new file name, you can control-z through all the work you done since you started the application to the last working version. If you put your PC on standby overnight, you can save the current version and then ctrl-z through several days of work to find the change that threw it. I've never lost any work as a result of it's foibles. Regards.
