I've been following Wine development for the last 6 months, mostly watching for improvements for the 2 Windows applications I actually care about -- Quicken and TurboTax.
Quicken has been mostly usable for that entire time period; however it's behavior has significantly improved. Far fewer hangs, crashes and other undesirable behavior. I won't enumerate the problems y'all have fixed, but the user-visible progress has been great. There's still some rough edges, but the improvements have been huge.
TurboTax was basically unusable until recently -- but when I returned from a short vacation and updated my wine sources, all the show-stopping issues with TurboTax had been resolved. Amazing.
The one issue in both tools that I still need to check on is both consistently ran out of GDI space, which I've hacked around with some tweaks to gdiobj.c.
There was a 3rd application I've been evaluating (RentTracker) which was also unusable in mid-Feb, but which appears to work flawlessly now.
I just wanted to let you know that you've made great strides recently and your work is greatly appreciated.
