In the last week or so, P and I have been having our browsers [Safari Firefox (Mac and PC) and IE] Slow to a halt with scripting errors and Flash problems.
A recent Error that Firefox for Mac displayed was:
"A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
Script: http://choices.truste.com/ca?aid=pott... "
Stopping Flash sometimes fixes the problem but it takes a while for the command to run, if the browser doesn't crash first.
