Not to mention aliens, octopi, burglars, and various other nefarious icons.
I run NT at work and XP Pro at home. Those OSs have a program called "Task Manager" that shows a CPU activity scale in the tray (next to the clock). A lot of those ads on the left side of the screen run my processor up to 100% usage.
When they appear on the screens where you type in your message, they even make my typing appear slowly, not to mention hog all the cpu time when it should be busy with other things.
I know b.c needs to make money, but a lot of the ads really are sucking up resources on my machines.
