I’m slightly saddened that no one else shares my pain.
I wonder if the symptom is partly OS-related. I use Windows 7; some comments suggest other OS’s may be unaffected.
This SDMB page (show who posted in a thread) ends up with a scroll-bar that doesn’t work at all (although the up/down arrows work); after a while a “This page has become unresponsive. Wait or Kill?” message appears. Firefox displays the page and operates its scroll-bar with no problem.
The symptom is most troublesome on very long pages, because there is no fine granularity. Yesterday I accessed a very large pdf (warning: huge file) and the scroll-bar was frustrating. The up/down arrows worked, but without a repeat-key function they were much too slow to scroll through a large file. (Admittedly, there are better programs than web browser to view a pdf, but a similar difficulty presents with giant html files.)
(I ended up trying to view the giant pdf with Firefox, but that has its own problem. Firefox was using almost 3 gigabytes of main memory before severe thrashing made me realized I needed to kill Firefox :smack: )
