[Closed] reduceKeys maxscript closes its own UI panel. Bug?

I’m having a strange issue with the reduceKeys maxscript.

I’ve created a little rollout panel that is part of a larger set of tools. But every time I run the reduceKeys maxscript, it completes perfectly, but then opens the Maxscript Listener window and closes my popout tools window.

This is a cut down version of the tools panel I’ve created, but causes the same problem:

firstDialog = newRolloutFloater “Tools” 350 100

rollout PreprodRollout “Pre-production Tools”
(
button btn_001 “Reduce keys”
on btn_001 pressed do
(
reduceKeys $.rotation.controller 0.4 1f
)
)

addrollout PreProdRollout firstDialog

Any ideas or suggestions?

Kind regards,
Peter Spence
