Can't resize screen horizontally nor diagonically

With a fresh wavelab 11.1 I can’t resize screen horizontally nor diagonically to make it bigger on a dual monitor system (set as extend desktop) on windows 10. Vertically works though, and making it smaller horizontally also works. I already tried the obvious stuff. Am I overlooking something? Any thoughts?

This is a showstopper, I will roll back to 11.0 if there is no solution.
best, Peter

This will be fixed in the upcoming WaveLab 11.1.10

Thanks for your quick response! Do you know when 11.1.10 will be released?

in 2 weeks.

Great, thanks!
