I had not tested the new version that releaed yesterday.
But with the older version I have a few problems.
The first point: My hardware and my system
I use at home linux-gentoo-2.6.19 [stable] and kde-3.5.6
My hardware are GeForce 7950GX2, 1 GB DDR2 RAM, 200 GB HDD, AsRock Mainboard, 10 and 100 LAN, onboard 7.1 soundcard...
then my internet connection: dsl ligh (76

Now my problems:
When I want to add a new contact in my friendlist the client crashed (with linux >.>

When I use the "toggle fullscreen" the client crashed (with linux)
When more than 20 people are on a sim, the client make a few problems and a few minutes later, it crashed, often the complete system
When we have ehm... 08:00 PM in Germany (20:00) and here in the USA all guys come online, the client will be really instable.
I have tested the windows client on linux with wine, but I need the QuickTime and DirectX SDKs... I don't get them.
I haven't cedega :/
So... can somebody ask me, what I can do for getting a "stable" client or reduce that often crashes?
Thank you

Best wishes, Tyranastrasz
Edit: I had forgotten my processor o.o It's an Intel Dual Core E6400 (2x2.13 GHz)
