I just purchased and installed MPEG Editor v2 Premium, did a quick test project, primarily to get the license, and make sure things worked, and they did, so I shut it down. I then tried to browse the internet using Firefox, but my firewall allerted me that TMPG MPEG Editor was tring to access the internet by sending commands to explorer.exe. The only programs that I know of that try to access the internet without the knowledge of the user, are securty threats. So when I denied access (via the firewall alert), my browser was inoprerable, unable to connect to anything. After a while trying to intercept this behaviour I was forced to de-install MPEG Editor 2 and reboot, before the internet was accessible. Is this behavior intended?

iono about that... sounds suspicious to me and I don't mean with MPEG Editor. Why would it access explorer.exe (your Windows explorer) and not iexplorer.exe (Internet explorer)... but anyway how is all that connected to Firefox and MPEG Editor 2P? give us some details...sounds like you might got a piggy back riding trojan off of MPEG Editor 2P.
