Isn't it working with wine? I don't think that client is so complicated to make it work...
I haven't tried it with wine. I generally have a distaste for wine as it installs a whole bunch of packages on my computer and then runs terribly slowly on my already crappy hardware. Wine is sorta like a last resort for me, as I said I don't even keep it installed. I don't know if anyone else has tried it with wine and had success. If someone out there has tried this and can say that it worked for them, that would make me slightly more interested in trying it out (so that hopefully I wouldn't have to install all of those wine packages just to find that it doesn't work on wine).
Sadly it doesn't work with wine, lobby shows up for a split second, then it crashes with this error:
err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr (nil)
Maybe there is a trick to get it working, pokerstars works so good with wine :/
