When debugging in chrome, the scripts are always paused in the debugger even if there are no break points set, and if the the pause is un-paused, it again pauses itself.
What can be done?
One possible cause, it that you've enabled the "pause on exceptions" (the little stop-sign shaped icon with the pause (||) symbol with in in the lower left of the window). Try clicking that back to the off/grey state (not red nor blue states) and reload the page.
