VRay Light Lister - No undo?!

[Morne]

Hi all

Just noticed this now on a 2014 scene at latest VRay. If I make any changes in the light lister and want to undo, the undo doesnt work
(it seems to totally clear max undo randomly also)

I hate it when 3ds Max undo decides to clear itself. I see the "undo 1 command" too many times!

hmm, it seems that undo is not supported for the native 3ds max Light Lister also.

Max documentations says

Not all operations are reversible using Undo.
