After every download from brokerage, bank or credit card, Quicken 2014 crashes. Fortunately, the downloaded data makes it into Quicken before the crash.
Nuisances: the screen is flickering *a*lot* whenever I change screens, and the screen refreshes are quite slow. Very annoying, especially when you're looking intently at the screen. That, plus a bunch of other annoyances that I've submitted to Intuit early on in the 2014 release cycle (i.e., a little less than a year ago). But so far, none has been fixed, and I've gotten absolutely zero feedback on my detailed problem reports.
At this point I'm hoping that the fixes make it into Q2015. If not, then I will be evaluating my need for Quicken, and whether or not I want to continue to support the company.
