Looks as there is also Tk bug. Perhaps on Windows (and Unix?) "winfo id" can return 64-bit integer, but the -use option works only with 32-bit integers.

Opened Tk ticket: http://core.tcl.tk/tk/tktview?name=5ee8af61e5 .

Serhiy Storchaka added the comment:

The other failure is not Windows specific. It can be reproduced if run test_tk twice. FontTest.setUpClass() incorrectly call parent's method and the root attribute is set in parent class. tearDownClass() sets the root attribute to None in child class, and this overrides parent's attribute. The test in the second run passes self.root (is None) to font.Font constructor, and this is interpreted as no the root argument passed.
