Try setting:
FocusOnHover = false.
Thanks Rumen for the reply.
Yes, there is a complex SQL query happening that takes time to execute but I am sure the page lifetime doesn't timeout. It is an issue with the Menu control. Even it occures when an AJAX action takes place, just mouse-over the menu and the AJAX event will be interrupted.
Hello,
I do not think this is the expected behaviour, this is most probably an issue but I am not 100% sure iti s related to the menu control alone. You say that execution of the click event takes several minutes. Why is that so? Is there a complex SQL query happening on the server?
There is a default page life size in seconds (I believe 30 seconds is the default) and if more than 30 seconds pass and there is no response from server, typically browsers cancel the event. Is this something that could be happening here?
