2.0 beta Bug?

[tkuypers at pandora.be]

Stack 1 has got a group named MyGroup
This group has got 1 custom property: pNewLoc

Stack 2 has got a button with the script:

On mouseUp
    Put MyGroupName into vMyGroup
    Copy group vMyGroup of stack Stack1 to stack Stack2
    Close stack Stack1
    put the pNewLoc of group vMyGroup into vLoc
    set the loc of group vMyGroup to vLoc
End mouseUp

The group is placed in stack 2 and stack 1 is closed, no errors, but the
position of the group remains unchanged...

When I enter the "set the loc..." command from the messagebox it works fine
When I enter the "set the loc..." command from a separate button it works
fine as well

Any ideas, anybody?
I guess this should work, but strangely enough is doesn't...

Regards,
