Matlab Dialogue Box showing through PTB

I programmed an experiment in Psychtoolbox. Participants will complete an experimental task and use the mouse to click on stimuli in on the screen as their response (which I created using OpenWindow, FillRect, different Draw functions, etc.). 


Whenever you hover over an icon in the toolbar on Matlab, a little yellow dialogue box appears that describes what each button does. Those dialogue boxes from the Matlab toolbar appear in Psychtoolbox "through" the display I created with OpenWindow. 


I'm not sure why this is happening and I can't figure out how to fix it. Any ideas?


still too vague.

at the very least please provide your computer specs, monitor setup, operating system and version, MATLAB version, and PsychToolbox version.

and, provide a minimal piece of demonstration code that exhibits the issue.
