Will the integration 3.08 and the latest version of flashchat seems to have cured this issue as a log off script now automatically runs on exit

Ahh excellent, I'll get onto that right away. Thanks as always Op.

another hint, the current integration gives url you currently have and places chat in forum. Might be more useful to change the url to the flashchat.php file directly and have it open in a new window. This has several advantages:

navigation is not hindered
members can view the forum for thread updates/moderation etc without coming out of chat
window is more easily resized (useful if you are multi screen or use a lot of open windows)

try it using WO chat room
