I can't seem to select "A Folder" when using Capture Assistant. I have no problems selecting "Startup Volume", "My Home Folder" or "A Volume", but "A Folder" just won't stick. I've tried hitting the "Choose" button below it and it does nothing. Any suggestions? Thanks!

I've tried, and I can't reproduce this problem (at least on the three systems I tried it on).

Try to reproduce it, and then send a diagnostic report (in the QRecall app, choose Help > Send Report…). It may be a compatibility issue with an earlier version of OS X.
