hi,
just builded ardour2 rev991, with prefix=/usr  vst=yes and fftw=yes.
i am able o start ardour, bur ardour will not exit in a way i am expecting.
so when i go to "close session" ardour just "freezes", and i am only 
able to kill it.
the machine is responding in the normal way, only ardour is "frozen".

here is the console output, it seems to me that it is something about wine:

and this is after pressing ctrl+c which will stop ardour:

and also generally, it looks for me that building ardour with vst 
support, makes the appi much more "fragile" than when built without vst.
does anybody else has made similar experience?

cheers,
doc
