uTool 2,0.062, Win7 64 multitrack playlist issues.

Thank you for your reply.
I cannot input any number in the field with that 0 sitting inside. That zero cannot be deleted/overwritten with another number, all I need 3 seconds wait time to replace my capo on guitar and change preset sound on a guitar rig.
Using uTool 2,0.062, Win7 x64 and Win10 x64.
Have a nice day, Laszlo.
Richard.
