Thanks!
I did a poor job of posting the issue. Rather I should state:
I can create a new account using the "+" button when I have a register open. In this case I need a new account to track a CD. HOWEVER, if I happen to have an item selected and don't completely leave the item, specifically if I didn't have a category assigned, Quicken will lockup/freeze.
I can be in another item, with a valid category, and I can add an account w/o and issue.
I know how to transfer between accounts, I was trying (unsuccessfully) to point out an edge condition where Q2017 locks up. Otherwise, the program has been pretty solid. A nice improvement.
Thank you for the fast replies. If I didn't know how to do a transfer they would have been quite helpful.
