Runtime Errors asking to be debugged?

Problem: Recently I have been getting allot of “runtime error” messages with different line code refernces that pop up allot while using IE6 or AOL’s browser, and sometimes even while not on line. I already installed the 5.6 new script version from microsoft in hopes it might resolve problem..But of course that would have been too easy…
Can anyone tell me how to prevent or stop all these runtime error messages? I also tried to debug them as they pop up but to no avail.. And I couldn’t tell you what was installed recently that might have triggered this problem. Any ideas on how to stop all these runtime error messages? Thanks, appreciate the help…
