Clicking one portal tab displays the iviews from the one next to it

Hello,

I have a very strange problem that I believe must be a bug. It only happens occasionally, but we have clicking on one tab and the correct iview is displayed but the other iviews from a tab next to the select tab are appearing. Also the incorrect tab is highlighted.

So Clicking Tab A shows the entry point iview for Tab A but the navigation links to the remaining iviews are for Tab B. Also Tab B is highlighted.

This error is rare and difficult to replicate. I believe the error may be related to our use of the Desktop Filters.

Any ideas?

Thanks,

Matt
