CR4 Topic Page Scrolling Problem

Guest here. I was going to register, but then this problem came up.

Since CR4 revised its website format my browser has been behaving badly when viewing posts.

I now find that one or more tabs fails to scroll correctly. It doesn't seem to matter how many tabs I have open, one or seven. One tab, and it seems only one, will always slow scrolling down to a crawl. The only way to scroll when I get to this tab is to place the mouse over the scroll button and hit the mouse button a gazillion times and wait for movement. This never happened before the site re-design. This tab may be the first one I look at, or any random tab in the lineup. Once I close the offending tab, the rest behave normally.

I am using Firefox. I typically browse the many topics in the daily email and open all I wish to read at once. Since FF uses a tab system, this is a convenient way to browse the threads and discussions.

Now, I am running an old system (not my choice) Win 98 on an X86 platform with 384 Kb Ram. I should mention that I usually have no less than four applications running at any time, and yes, that does tax this old system a bit. But since this problem did not occur before the CR4 revision, what might be happening?

Thanks
