This works fine on my end across all browsers.
What I can advise at this point is:
- make sure you attempted my workaround that calls a couple of RadEditor's methods
- upgrade to Q3 2013 SP2 because it handles some breking changes Chrome 32 introduced
- once Q1 2014 comes out, upgrade to it, because it will bring improvements on the resizing of RadEditor
- try using a RadTabStrip and RadMultiPage instead of jQuery tabs to see if this makes a difference. The OnClientTabSelected can be used as an event to fire a function that will repaint editors, if needed.
