Spectrum editor text tab (T) crash Wavelab 11 on windows 10

When I try to use text tab on Spectrum editor wavelab crash.
Win 10 21H1, Intel I7 coffee lake, Tascam US 20X20, 32 GB Ram.

Thanks for the report. This needs to be addressed for WaveLab 11.0.20

OK. Thank you!

unfortunately version 11,0,10 did not solve the problem on my computer.

No, you reported the problem after 11.0.10 was finished.
But 11.0.20 solves the problem.
