Oh, sorry. I did't see that other post.
Could it have something to do with plot properties? If a greate a plot with like:
Then the '.k' will cause all other plots in tabs, to be traced through the layer of tabs. If i use 'k' - thereby skipping the '.' - all works fine.
Yes I have seen this problem, please see my comment from 12 Nov 2013.
Plotting in a UIPanel improved the situation but didn't resolve it completely.
It maybe also related to @Stephanie's problem below 08Sep2014. I have not tried investigating that solution/work around, if you come up with a solution, please post.
