ej.function crashes everytime in M4L

Hi!

I really love the ej.function object!
But unfortunately it doesn't work properly in M4L.

I'm on windows vista ultimate 64, ableton 8.1.3 and Max 5.1.4.

It often crashes if I'm in editing mode and have opened the ej.function help.

AND it crashes ableton if I have a pattr object binded to the ef.function:
- I change something in the jsui.
- save the live set
- if I then open a new/another live set it give me a serious program error on closing the old one.
(- reopening the old live set works and also reinitializes the old jsui settings.)

Have you guys experienced the same?
Is there a work around?

thanks,
ring
