REW crash to desktop when selecting input device

When I start REW with my Tascam US-122 plugged in, I get the following error:

No input mixers available
supporting PCM_SIGNED 48000.0 Hz, 16 bit, stereo, 4 bytes/frame, little-endian

If I click OK the program opens, but when I go to settings and look at input devices for 44.1kHz, I see four items in the pull-down list:
Default Device
MacOSX, Core...
blank
blank

("blank" means a blank line). Presumably the Tascam should be in one or both of the blank lines. Selecting the upper blank gives a javascript error or sometimes a crash; the lower one causes a crash.

This is a Macbook Pro running OSX 10.4.11. I've got the latest drivers for the Tascam.

Have you checked the Tascam is enabled under "Applications/Utilities/Audio Midi Setup"?

Under 10.4 you need to set the sampling rate as 44.1kHz and select the default input and output. Only the on-board audio input is available to java apps like REW, you need 10.5 to get Apple's fix for that.

OK - I'll work around it. Thanks.
