Im not gonna delete this thread (may be some one else will), cuz the solution i found only stops the error msg from commin', but it still occurs, now i wanna know what's causin it.
In Internet Explorer, click Tools and then Internet Options.
Go to Advanced and check "Disable script debugging" and uncheck "Display a notification about every script error"
this should work perfectly, i've had it a couple of times on different pc's when installing office 2003
