I’m using the plugin withInDesign CC 2014 on a MacBook Pro, 2.9 GHz i7, 16 GB RAM with SSD HD with OSX 10.10.3.
When I have the data palette open to work with it, InDesign reacts really slow. It takes up to 5 seconds to do a requested task. My Excel file has around 40 columns and 75 rows and is grouped. Nothing too special.
This makes it no really fun to work with. Without using the Easycatalog plugin, InDesign works fine and fast.
But this is just on my mac in the office. I’ve installed the plugin as well on an iMac from 2008, 2.4 GHz Intel Core 2 Duo with 3 GB RAM under OSX 10.10.3. And it works like a charm. No problems at all, no delayed reaction time.
So I already reset the preferences file and have no further idea on how to fix this.
