Bspus-I know exactly what U mean!
WinUAE 8.8 r8 seems the only stable, working version 4 me too.
Granted I'm operating off a Celeron 266 at present so I'm not trying to be too harsh of WinUAE, later versions probably need more power than that.
I haven't even bothered trying the 8.16 releases yet, I wonder if they're worth the download??
Ahh, in a perfect world please let some programmer with loads of free time access to WinUae 8.8 r8's source code & improve it- just a touch-for games compatibility & then at least an OCS/ECS version of WinUAE would be complete...
