I use FlexPro on a computer with 3 displays.
After suspending the computer over the night FlexPro is minimized to one monitor like all other windows as well.
The problem is that the border of the opened diagrams are always reduced to zero on the left and right. So I have to open the properties of each diagram and set a value a bit above zero. After that the borders are corrected automatically by FlexPro. The command to set the borders automatically is always set.
BTW: Where can I find the changelog to the different versions of FlexPro.
