Hi guys,

Though Bob is quite correct, in that an 'overflow' is a memory issue, what the error is referring to in this case (somewhat confusingly), is that memory allocated within the webpage script itself, has been exceeded by some operation its trying to perform.
This isn't related to lack of memory in the machine itself, but rather the script on the AT webpage is badly written, and is exceeding its self imposed memory / variable specifications.

There's a few ways to resolve this, it could be related to the browser itself, or your Java version (suspect its this in your case Peter because the popup windows and image things are usually Java based - as Norman also mentioned).

What web browser are you using?

Hi Ciaran

I am using the ordinary built in one, I have tried Google Chrome and one or two others but they have all caused problems with the computer so I have had to delete them.

CCleaner is free and I use it regularly to shift out any nasty cookies or spyware that might sneak in. I have also found that AVG provides good protection for free.
