Description:	I have an strange behavior that it invokes the command without stop. I write the next code in the wish8.6 console: ttk::spinbox .sb -from 0 -to 10000 -command [list ::danitest] grid .sb proc ::danitest {} { puts "inside" tkwait variable ::danivar puts "outside" } Then, I do a single click on any arrow. The command is invoked and I can read the message "inside". Now, the process is waiting to the change of my variable danivar. In this momment, I write in the console the next code: set ::danivar 1 and when I press return I see that the message "outside" is shown, and some milliseconds later, the event is recalled (and I can read again the message "inside"). This behaviour doesn't stops. I don't know if it is my fault or there is an error. I have the same behaviour if I use the command error instead of tkwait.
