I recently downloaded update to Opera 4.0. Since then I've started having problems. First it started with problems searching. I keep getting a message "the website not responding' or "the website responding too slow". Sometimes the Internet stops altogether. Then it starts up again then slows down again. I have also experienced stacking of different pages a few times. I have an excellent anti-virus program, 2 great anti-spyware, an anti-exploit, and an ad-blocker. I also have 2 other programs to warn me if anyone is trying to load files on to my computer without my permission. All the software is up-to-date and are compatible with each other. There's no problems with the Internet in my area, and no problems with my provider. My other web browsers are working fine -- I have 3 others. Another words, the problem must be with Opera 4.0. I contacted Opera and I'm awaiting their response.

I'm experiencing same problem -- "this site can't be reached" I'm not having problems with my other browsers. There's no current problem with the Internet service in my area nor the company. I also experienced stacking of webpages a few times. I have all up-to-date anti-spyware (3 different programs) and an active anti-virus. Everything is compatible on my computer and I have ample space, etc. Another words it can't be anything but Opera. In my case it started happening after the update to Opera 4.0.
