BUG: External FX crash 6.0.0 and 6.0.1

1 Start cubase 6.x
2. New empty project.
3. Setup external fx (F4)
4. Add a stereo in/out effect
5. Set the delay field to empty.
6. close the window.

(OSX 10.6.6)

It didn’t do it here on pc

I’ve had something similar happen with Windows 7 64 bit, running Cubase 6 32 bit.
Add external fx plugin and crashes to blue screen. Has happened twice, but not everytime I add an external plugin.
