Vray NEXT - IPR bug up slate material editor - cant delete nodes

Hello guys,
this one is very annoying.
Most of the time when i work with IPR and when i STOP it to make some more rough change in the material, i CANT DELETE the material nodes - i can only rewire but no chance to delete it.
Sometimes this goes away in time but most of the time i have to reset Max.
Can someone replicate this?
I am getting this in all the scenes i work with.
MAX 2019 here and Vray lates stable nightly.
Cheers
M

I’ve been having problems deleting nodes in material editor lately too. It always resolves by closing material editor and reopening it again. Not sure if it’s IPR or Max acting weird.

I also have had this problem for ages and never worked out what was going on. Now reading this if i close IPR window i can then delete the nodes. Is this an IPR problem ?

Same here as well.

Reproduced it here and will make a note about this. Thanks.

I’ve encountered this a lot too, and I don’t even use IPR. What I do, so I don’t have to close Max, is minimize a few times, show desktop a few times, close and reopen material editor, and voila it’s back to normal. It’s a windows thing.
