Opera 9.02 closed unexpectedly after the Net-connection had stalled

I have Internet through cable, and the cable isn't installed according to specs. It works, but my ISP says there are some values that aren't quite right. This means that once every day, the connection stalls. The cable modem is Motorola SB5101 and I use the USB-cable to a Targus Notebook Hi-speed 4-port hub to my computer.

Was looking at this site (http://www.zdnet.co.uk/talkback/0,1000001161,39261437-39001068c-20071246o,00.htm)
when this happened today. I pressed the link Next Comment and got a 404 page due to my stalled connection. I unplugged the power and re-inserted. Then pressed the back button in Opera and Next comment on the site. The computer started working like hell. (P 400 Mhz, 192 MB RAM, Ubuntu 6.10, 6.2 GB HD) I minimized Opera, then maximized it to see if that helped. Then I used taskbar (bottom bar) to close the widget Currency Exchange by right clicking it and choosing Close (Norwegian language pack it's Lukk).
Then the message that Opera had closed unexpectedly came, and asking to report a bug.
