TR4A - Thanks. I have had a look there but can't find anything (as yet) to help me out. To be more specific, when I click on the URL you posted (or the link from HandyAndy) the window which pops up is blank except for the toolbar. The address window is blank also. If I copy and paste the URL into the address box it loads OK.
HandyAndy - Popups popup just fine. Unfortunately that is not the problem. I use a different killer on my own computer but will check out your recommendation. Thanks.
Cheers.
