Delay in text appearing

Hey Scrivener,

I have a problem with the text not appearing for close to fifteen seconds when typing. My problem only started with the upgrade to 1.3 Beta, with the first Beta there was no delay. It is very frustrating as seconds or so later will my text appear and maybe there is a spelling mistake, it really breaks the flow of typing!

I am running Vista and have also turned off the spell check to no avail.

Any help appreciated!
