Hello,
I've got problem with moving layers from RGB(8bit) image to the other RGB(8bit) image.
I found out the problem, it is filter "Color lookup".
If there was layer "Color lookup", it is impossible layer move "drag&drop" to the other image. This way, I can't move folder, with included layer "Color lookup".
I tried on empty image, and I'm sending screenshot with warning
I've got MBP last 2010,
OSX Lion 10.7.3, Intel Core i5, 8GB RAM
Photoshop CS6 Beta
thaks for feedback
Thanks for the report vaclavfous, I'm able to reproduce this, thanks for noticing this!
