Beginning today, tabs began to stop responding for no reason I can isolate. Main page, Forum index, PATV. Thought maybe it was doubleclick ads or flashplayer related, but forum index seems to have no ads or anything fancy at all.
I'll have multiple tabs open, with 2-3 PA tabs. In a PA tab, click on a link to navigate elsewhere* on the site. Tab freezes. Any attempt to navigate on other PA tabs will result in freeze, any new PA tabs will freeze. This has no impact on other tabs, and persists in a new instance of chrome with no other tabs. This 'lock out' will either last for a minute or two, or until I've killed all open PA tabs. I haven't seen it resolve without killing all existing tabs first.
*It has been triggered by clicking on a forum (2x), going back to the main page(1x), and going to PATV(1x).
