Playing with XML in an InDesign template tonight when I figured out what was causing one of my pettiest pet peeves.
The Problem: When you choose Map Tags to Styles you get a jumpy, flickering beachball/cursor, lasting for a very long time. I’ve waited more than a minute to regain control of the application. And the flickering back and forth between a normal cursor and a beachball is more irritating than a plain spinning beachball.
The Culprit: Preview is checked in the Map Tags to Styles dialog.
This is a sticky application preference, so InDesign will remember if you left it on last time, even in a different document.
My advice is keep Preview unchecked and test out your mapping before opening the dialog box by applying some styles manually. You still may suffer the flicker when you click OK, but it seems to be shorter in length when you map specific styles. It’s almost like Preview is loading every style into memory. And this way, you only flicker if you choose to go ahead with the mapping in the current document. If you do Preview, uncheck it before leaving the dialog.
By the way, my flickering problems were always on a PowerBook G4. The problem may not happen as much on a speedier Intel. I’ll have to check that out when I get a chance.
