I don't think that's a CWM issue. Apparently it is the same way for every non-stock recovery image. I imagine it has something to do with the backup recovery image that tries to auto-flash itself. The bootloader probably tries to access it, can't, and hangs on it. Outside of a possibly putting the CWM image in it's place (can that be done?), we may need a custom bootloader to fix that issue.
