I am using aca 2008.
other than viewing png files, I don't see what else you can do with tp's in the design center.
Also I noticed, if I copy my entire catalog folder. go home and erase that folder, and add the new folder in, when I refresh everything comes in at the right spot. but what I am afraid of is that, at home I use one hd, with different partitions, at work, that drive is over the network. files will not load correctly, I think one time I tried that, and all the images on the tp, did not load.
