Not sure if this is the correct method for reporting problems - please let me know if there is a better way.

I've recently been trying 3D modelling in ACAD Mac and noticed that the materials library window doesn't seem to function properly when applying a search filter. I noticed it with 2015 and then installed 2016 and it behaves the same way. When typing in the search field, the text just enters a new command and doesn't go into the serach field. No amount of clicking (or copy/pasting) could get text in the field, it kept being entered as a command.

Also, it seems to be possible to anchor the Materials Library window to the side of the screen in a way where it is not doen correctly. I can't reproduce this consistently to know what is happening. The attached screenshot shows it acting up. It has slotted itself between the Layer manager and Properties windows (there is a small part of an 'X' to close the Materials library behind the overlapping part).
