Just made a fresh os3.1 install + afa 4.2 under Winuae.
At first I had the same problems as you. Then I realised
I started the afa preference program from the cli,
because it's icon didn't show up in WB. I replaced the
icon-image of the afa prefs program and after that I
noticed with Icon-info,AFA prefs has a huge stack size set.
So this time i started the prefs program by doubleclicking
it's icon and it didn't guru anymore.
So I selected a skin, saved my settings and rebooted.
The skinned WB menubar shows up, but as soon as a window
is opened on wb I get a guru message. I didn't get any
further than that. Tomorrow I will try to look into it
again. *EDIT: Figured it out: I had to tick the use FPU
68881 option in winuaes cpu and fpu settings.
The skinning does now fully work.
The only thing that doesn't work is afa's ability to
show PNG icons. They just refuse to show up under my 3.1
config. I also own amiga forever, and under the 3.5/3.9
config of AF2006 it does work, so I will have to look
further into that.
BTW I use Winuae latest beta, so things may work different
for you, because I don't know what version of winuae you
use.
