Script has been added to force IE10 to work like IE9.
It worked but was slow to react so i move the script in the forums headinclude template to be read earlier by your browser.
i'm sure it is VB/tapatalk to blame HOWEVER the problem arose by a earlier version and the tapatalk script has been changed to accommodate it so shouldn't have happened.
Clearly it did and i apologise for that and i'm sorry it took so long to fix but i'm glad we got there in the end.
