Mouse clicks sometimes not responsive

Hi,

Are there some odd reason why the mouse might take a few clicks to be responsive? I had the mouse be responsive when clicked on a particular image. This image is listed under ‘clickable’ for the mouse (i checked). Earlier, a single click would register a response. Now, I need to click a few times before the response is registered. Is there some reason this might be this way?

thanks

OS (e.g. Win10): mac sierra
PsychoPy version (e.g. 1.84.x): 2020.2.3
Standard Standalone? (y/n) If not then what?: scratch build

Assuming that the window is full-screen, this could be due to some conflict with custom code that interferes with a button click before the mouse component is able to process it.
