I have a Mathematica 14.2 notebook open with a Do loop over 12.000 fields of a list.The code runs forever. Particularly annoying is that during execution the whole screen is no longer accessible by the mouse. Neither the Mathematica notebook itself can be reached, e.g. for termination of the running calculation, nor can any open window on that screen be used; only a second monitor works ok. I think this is a problem!
