Hello Peter,
Thanks for your reply. I have made an easy sample to reproduce the problem. You can download it here http://xbox.team.free.fr/Debug.zip
Just run index.html and then click a lot of time on items “Link 1”, “Link 2”, “Link 3”. The exception will appears.
I have made test under chrome and firefox 13.0.1. The version of jqwidgets is 2.4.1.
Thanks in advance,
Marco
