What web browser are you using and what version?
One more thing I strongly suggest you update your Debian system to sarge or sid. Woody is stable but all the pkgs are old. woody is really great for a server but kinda lame for a desktop workstation. it's easy enough to update so let us know if you are interested in updating I'll help you out.
Sarge is the testing release and Sid stands for "Stays In Development" it's the unstable release. I run sid ,it has the most current pkgs and it sometimes breaks little things but it's easy enogh to fix and it usually just needs and apt-get update and apt-get upgrade a couple of days later to work it out. I've never been left with an unusable system using sid.
