Clicking an entity causes a painfully long freeze

There were a great number of reports a few years ago on this forum of this long hesitation on left clicking in Windows 10.

I don’t remember if it was ever fully solved, but there were certainly a number of solutions that worked for some people. See for example:

I didn’t follow it closely, since I was by then using a Mac, but you might find some useful suggestions in that thread, or search the forum for ‘select tool delay’ or ‘left click delay’.

It’s unlikely in the extreme that if it is a bug in Make 2017, rather than in Windows or display drivers, it will ever get fixed - Make has received no updates for years, and won’t in future either.
