How much RAM do you have and how much free space remains on your HDD?
Using a pc (Win 7) with Firefox.
Trying to figure out what is causing my cursor to sometimes briefly hesitate & change into a spinning blue hoop. It doesn't last long, but it happens fairly often & is annoying.
I've tried clearing the cache, cleaning with Super-Anti Spyware & CCleaner. Not sure what else to do.
