How to hold right click context menu active?

Hello. I have a GUI that makes 7 figures iteratively visible and invisible to making P300 Paradigm for mouse control. There is a mouse action or movement after any iteration. My problem is that after right click all 7 figures minimized and I loose my P300 paradigm figures.

How can I remove the problem and restore the figures on the screen?

And also I want to hold the right click context menu active for the next iteration. I mean I want to have contex menu for right click hold and I have my P300 Paradigm continues to move the curser over context menu and finally click on it.

How can I do it?

Thanks..
