[Daniel Law]

New submission from Daniel Law <danlaw9000 at googlemail.com>:

python 3.6 and also found it in 3.7.3, on windows 10. when a main application window built with Tkinter has a modal top level window (transient, grab_set) if it is minimised (which get blocked unless you click show desktop or shake another application around) any and all atempts to reopen or switch to the application again are blocked and the application has to be closed and reopened.

gif attached of this in practice.
