How do I stop a long process on Windows 10?

Hello all,

How do I get a LibreCAD process to stop when the rotating circle stays on for a long time?

Here are the details:

I am not sure if my subject line is clear. Let me tell you what happened last night.

BTW, I am on Windows 10, 16 GB memory, I7 processor.

I tried to move all the objects in my drawing representing the interior of a food trailer to a different location.

I chose all the objects in all 7 layers with ctrl+A.

Then used the Move/Copy command icon.

LibreCad started displaying a rotating circle.

I waited 45 minutes, nothing happened.

Left the computer on, went to bed. After three hours the computer was supposed to go to sleep mode.

Got up this morning, started the computer.

LibreCAD still had the rotating circle.

I finally had to kill the LibreCad process with the Task Manager, losing the results of about two hours of work.
