Sorry it took me so long to get back, anyway..... this is something that happened to four of us who all bought our PCs at the same time (we all got HPs but different models) and one of the windows updates fixed it. However, I'm the only one whose PC wouldn't accept SP2 and I wound up reinstalling the original WindowsXP and so the problem with "script errors" arose again.
The SP2 situation has been a NIGHTMARE.... the three times I tried installing it it would tell me that the system was unstable and to remove it. I wound up taking it to "Best Buy" where I bought it. First they told me it was the WindowBlinds and those programs that were interfering with it, then they said it was my PC that wasn't compatible with SP2 , but HP said that was not true either........ To make a long story short, after keeping my PC for about three weeks they told me they had installed SP2 with no problem, but three days after I got it home my PC stopped working. In frustration I reinstalled the original WindowsXP and that's when the script error thing started again. I have a suspicion that Best Buy mickeymoused SP2 into my PC.
As I said, I do have "Display a notification about every script error" unchecked. I have done a search at "Microsoft Windows Update" site I just can't figure out which of all the patches/fixes is the one I need.
Since it happened to all of us I thought maybe someone here would remember it happening to them and know which fix to get.
I know its a long shot but I thought I'd give it a try.
