v6.0rc4 "Set mouse modifier..." command is still very slow (FIXED)

[wwcdgm]

The example script uses only the "Set Mouse Modifier..." command. They run very slowly, and they cannot respond in time when switching quickly between these three modes. Probably delayed by 2 seconds.

It can be painful to write notes.

This problem exists in Windows 10, I have tried other Windows 10 systems, they are all very slow.
