Re: Script keeps stealing focus from me!
There's not enough information to give you an answer. Your computer could be too slow, you could have OS problems, a memory stick could be acting up, a bad browser update, or this could be malware.
Assuming you can rule out the hardware, you can click Ctrl-Alt-Delete and open up the task manager, check out processes running. Sort by CPU and see if any particular processes catch your eye when you have this freeze up happen. Then sort by memory and do the same. Maybe the culprit will become obvious. Maybe running CCleaner will help, if not visit the malware sticky.
