[Wine] Problem with multiboxing WoW

[palpitations]

I've been trying to open up multiple instances of WoW under Wine for a while now...  I can get two copies open at once without a problem, but I run into issues when I try to open a third.

Some background:  I'm running each one from a separate install, not trying to open them all from the same folder.  I'm using Wine 1.1.2, and the latest binary nVidia drivers (173.14.12).  I've got 2 GB of RAM and an nVidia 8800GTX with 768 MB RAM.  I've got a Core2Duo E6700 (2.66ghz stock) that's phase cooled and overclocked to 3.2ghz stable, but I've brought it back down to stock values for testing.  I'm running Ubuntu Hardy, 2.6.24-20-generic, and I've disabled Compiz for testing purposes.

Now then...  I can open up two instances of WoW with no problems whatsoever.  When I go to open the third, I end up with only the window borders, and nothing else.

The output from the third window is as follows:

err:alsa:ALSA_CheckSetVolume Could not find 'PCM Playback Volume' element
fixme:mixer:ALSA_MixerInit No master control found on SAA7134, disabling mixer

The two windows that work are identical up until this point, but then add this:

fixme:ras:RasEnumConnectionsW (0x13c7f0,0x7baed93c,0x70279524),stub!
fixme:ras:RasEnumConnectionsW RAS support is not implemented! Configure program to use LAN connection/winsock instead!

fixme:imm:ImmReleaseContext (0x20026, 0x1459e0): stub


If anyone has any ideas, I'd love to hear them...  I just got handed a third account, and I'd love to use it to 3-box and level in preparation for WotLK ;)  I've been prodding at this for a few days, and searching all over the place...  Unfortunately, the number of people multiboxing on Linux is pretty damn limited, it seems ;)

Thanks in advance!
