When using Copy command, no matter if it is finished with ESC or ENTER, the last copy disappears. Here I will attache the informations given in the command line:
Command: copy
[FILter]/<Select entities to copy>: 224003.7066,130175.7924,0.0000
Entities in set: 1 found
[FILter]/<Select entities to copy>:
1 found
Current settings: Copy mode = Multiple
Specify base point or [Displacement/mOde] <Displacement>: 223649.4152,129848.5231,0.0000
Specify second point or [Array] <use first point as displacement>: 223018.8965,129848.5231,0.0000
Specify second point or [Array/Exit/Undo] <Exit>:

Invalid key

In a new drawing it works properly, but if I open any of my previously created file (which were created in an earlier version of the CMS Intellicad) the problem persists. I have to use my old files.

Thank you in advance for your help.

What version of CMS IntelliCAD are you running?

Please send us a sample drawing for testing.

This is the version I am useing: 13.0.737.158051.PE+.VC17.x64.CMS130
