RMC tab misbehaves on Windows #196
Description
On Windows only: the 1st time the RMC tab is used, the widgets on the page do not work. Navigating to another data tree item (or tab?) and then returning seems to address that.
What is different about the creation of the RMC tab? Can that be fixed? If not, perhaps the code that initially creates the RMC tab page contents can be modified to add a workaround.
GSASIIphsGUI.py is the biggest G2 file by far (17K lines, almost all are under 10K), it might be time to start moving some of the code in that file to separate files.
