Ok Albert ,
Here from the link in the catbox.
I'm getting the infamous X in a small white square instead of seeing smilies.
In the "Advanced" post area the selection box shows the X in a small white square with the name of the smily in text beside it.
I have had a few slow windows but overall the speed has been OK.
I'm using IE 9 .
I also tried Opera & it is not loading the catbox at all .
The line with "Quick Links , New Posts ,etc" changes to different names when left clicked & doesn't work . This Opera is the latest version.
I uninstalled FF a couple of weeks ago so I can't test with it.
