I don't know where to look for known product defects/issues, so I am asking here.
Occasionally the Layer States Manager loses the icons for the buttons (see Attachment).They start off being there, but as you mouse-over them they disappear. It's just the images - if you mouse-over where the images are suppose to be you get the tip text, and the buttons do still work.
An AutoCAD restart does not fix - I have to restart computer.
I have plenty of RAM, and a capable video card.
Thanks,
