Kernel panic with PB3 during Abbyy OCR; crash report filed

First significant issue I’ve experienced with any of the public betas. Kernel panic occurred while Abbyy was attempting to recognize a handwritten note, and I was adjusting Afloat window viewing preferences. No other applications open at the time; running Leopard 10.5.6. Crash report filed about an hour ago, and I’m now doing crash recovery system maintenance with OnyX.
