beta3 OS X: taxing the CPU at min. 40% permantently

[arglborps]

I have no idea what causes this, but Moho 5b3 even when supposedly sitting idly in the background doing nothing is taxing the CPU with 40-70% permanently.

Since I'm on working mainly on a PowerBook this is not ideal, it'll eat my batteries in no time and the machine gets rather hot after a while and the fans start running (which usually on this machine really only run when I play Unreal Tournament or render some 3D stuff).

I don't see this. Activity Monitor shows about 1-3% CPU usage constantly if i go in and out of the progam and eventually drops to none. OS 10.3.5 on a PB G4 667

Spoke too soon. Left the mcahine doing nothing for an hour and when I came back the cooling fan was running full blast with Moho using about 45% of CPU. A sample of what it was apparently doing:
