Page becomes mouse-unresponsive

Too often the requests to switch tabs, load results or graphs (I have noticed this mostly in the wuid results section) - the ecl watch page becomes unresponsive to mouse gestures.

For some reason, pressing tab, and using other keys (such as arrows), can lead to changes on the page, but the mouse becomes useless in that context.

It seems the only way to resolve the issue is to close the browser tab/window - in which case all the current searches, opened wuid etc. are lost.
