While browsing in the e-shop app to find the PayPal functionality I am getting this error frequently. I am not editing anything, I am just browsing a5 pages and try to get an idea on how the e-shop works...

The message is a Runtime Error in Line:299 Error 'top.topFrame.document' is null or not an object. If I try to go on, all sorts of errors pop up, like Line 449 Unterminated string constants etc etc etc.... I have to terminate A5V9 and after that I have to reinstall the e-shop as the DB seems to have gotten hit or not closed or whatever....

Ideas?

Cheers
