Hi there,
Thank you for your attention.
I use the monitor built in the notebook computer, Windows 11, scaling factor 100 percent, text size 125 percent, resolution 1920x1080 (native). Intel Core i7-9750 CPU @ 2.60 GHz, installed ram 48 GB, NVIDIA GeForce RTX 2060. (I really don't understand these specifications!)
This morning (it's afternoon now here) I was informed of the new version of Cakewalk Sonar, installed it. I checked the lyrics window again and the editing function is now back to normal (the keyboard was working again in that window). I don't know it it's related to the update or not?
Problem gone, Thank you very much....
