Weird really, I've been using it for three years and only just the other day has it started causing me grief.

Went back to one of my feature length scripts (I'm gonna revise it, and see about registering it, then sending it out) - I decided to try out "Revision Mode".

Quite quickly I got a blue screen of death. Restarted. Tried again, and the computer restarted itself. Then tried again last night (turning revision mode off, using a fresh copy of the file I was altering) and it simply froze up (was playing music at the time, so a sort of stuttered audio resulted).

I'm thinking it's one of those weird cases where a piece of software that has worked fine decides to be an arse.

So I'm thinking:

1) Re-Install Final Draft completely.
2) Maybe the .fdr file - from which I make a copy (to be renamed and revised) to another location - has somehow corrupted.

I'm thinking it's more than likely #1 ... but was wondering if anyone had any other ideas, or had experienced such a thing themselves?
