I've been using Skype on my new 1.83 CD 1GB RAM MacBook for about 2 days now, at times with video call. Last night, though, while talking in Skype, I noticed my iSight video image slowing down into slow frames. This was unusual because the other times I used the video for calls, the video feed of me was flowing quite smoothly. I checked Activity Monitor, and it showed Skype at 53%, 87% and as high as 93% of GPU! What!?! And the threads section was hovering around 32. The only other programs I had open were iTunes and Safari. They didn't seem to be moving slow as if affected, but I'm scared. Surely this cant be ordinary though. Whenever I check Activity Monitor, the %CPU is usually around 1, 2, 4 or as much as 12 sometimes with Firefox. Can you tell me what's going on, please?? I appreciate your help.
