I have a map with several (~16) callout text elements in the layout. I realize that leaders & background, etc., add processing time, but things have slowed down considerably since upgrading to 10.2.2. (moving, selecting, opening the properties window, everything!) No difference if this text is in the data frame or layout. I've resorted to trading desks with a colleague who's still on 10.1 to make edits.
Is this a known/common issue? Is there anything I can try without reducing the amount of formatting or kicking a coworker off their computer?
