What is this?

[Anonymous]

This constantly pops up when i hide, unhide, freeze, copy, instance and when i use the right-click menu. I've never seen this in my life.
I re-installed Max because it never opened when i tried to. This has popped up ever since

Hi,

There appears to be an issue with the Forest Pack plugin - specifically the Select Custom Object. You might try reinstalling it or posting over at the IToo forums.

I did find this post that may be similar to your issue

Here's the whole search - may be more info

I've located and fixed the problem. Turns out the usermacros in a hidden folder were causing it.

Turns out some of my folders were hidden. Thanks for the info!
