@TFate, Oral B, =ABS= SparhawK:
I don’t have any trojans or spyware installed. I regularly run Adaware & Spybot anyway, and also keep a program running called WinPatrol that trakcs (most) unwanted changes to registry etc. I know not to use broken software such as Outlook or Internet Explorer, and am very careful to keep my system free of that kind of junk. I did another scan with Spybot and Adaware just to make 100% sure, and they didn’t find anything except some harmless cookies. Thanks anyway 
@Ragnar_40k:
I’ve tried deleting the ETPro folder, and have reinstalled a fresh version of ET twice, but no change.
@$pence:
Tried this too, disabling PB has no effect.
@chr0nicles:
This sounds like it would have worked, thanks! But, unfortunately my problems have ‘evolved’. Now things are much worse…
When I start ET now, things are OK for a few seconds but then ET freezes up. It will play a 1 second loop of whatever audio was playing at the time, and lock up just the way it does whenever it crashes, only this time it doesn’t crash and after about 20 seconds it kicks into action again for about 5 seconds, and then locks up again.
I’ve noticed two strange things, in Task Manager my processor usage goes right up to the maximum which is probably the reason for ET freezing (it’s an XP3200+ so shouldn’t be getting anywhere near maximum), and also if I click to another window and leave ET as the inactive window then it runs in the background fine (I can see the text scrolling or the timer moving, it doesn’t freeze) but then the moment I click back to ET and make it the active window, it will freeze again.
So I have no more crashes, but cannot play ET for even 1 second anymore. As I’ve said the following things make no difference at all: changing my graphics drivers, reinstalling ET (even deleting all trace of the old one), disabling PB, using ET 1.00 and 1.02, etc.
I’m starting to think my Radeon is broken
(this is the only thing I can think of, although my friends and I were playing Pro Evolution Soccer 3 for the whole of last night and didn’t have a single problem).
