Thanks, I have already reloaded and reinstalled 3x the core and plug-ins, without more success.
I posted it here as I had the same problem with 1.0.3.
Finally I think that it's a problem in the combination of:
1. laptop which is not the top most
2. xampp 1.7.1 not as performant as 1.7.3
3. CBSubs quite hard in loading his processes
Why that conclusion?
1. for the laptop, it's because on my desktop, that I mounted quite perfomant, I don't have any problem
2. for xampp 1.7.1, it's because, even on the laptop, I don't meet such problem when installed on xampp 1.7.3
3. for CBSubs quite hard... it's because, when loading CBSubs, it always let the browser navigation toolbar flashing more than usual.
Let say that solving the problem is quite impossible, but getting round is possible
