The mouse in Illustrator selects and deselects as it moves over buttons and cells:
1. In Graph data the cells the mouse passes over go dark grey if not already selected, then deselect if they are selected. This makes it very difficult to use the data cells.
2. In Layers window, where I may have 100s of layers, I want to hide one layer or more which are not necessarily adjacent to each other. Illustrator hides all of the layers it passes. It is very difficult to click and unclick the show/hide button (and also the lock button). Ditto with show or unlock toggle layer. I had to start up in Lion in which Illustrator does not have this problem in order to get a job finished in time.
Seems there needs to be a fix for Illustrator to work properly in Mountain Lion.
Has anyone found such a fix?
