Idle's Open file dialog is not modal.
More than one can be open at one time.
The all open as the same place.
They can all be hidden by other windows, including the parent, 
especially if the parent is full screen.

These might or might not be design bugs, I do not know that any are 
implementation bugs. They are definitely minor issues compared to some 
other Idle issues.

These are not modal.

Easily investigated from within Idle itself, using Find in Files Alt+F3 
to search for tkFileDialog in idlelib, which became tkinter.filedialog 
in 3.x.

Searching 'tkFileDialog' in lib/idlelib/*.py ...
lib/idlelib\IOBinding.py: 7: import tkinter.filedialog as tkFileDialog
lib/idlelib\IOBinding.py: 496:             self.opendialog = 
tkFileDialog.Open(master=self.text,
lib/idlelib\IOBinding.py: 516:             self.savedialog = 
tkFileDialog.SaveAs(
lib/idlelib\configHelpSourceEdit.py: 8: import tkinter.filedialog as 
tkFileDialog
lib/idlelib\configHelpSourceEdit.py: 94:         opendialog = 
tkFileDialog.Open(parent=self, filetypes=filetypes)
Hits found: 5
(Hint: right-click to open locations.)

As the output says, a right click will take one to the usage sites.

I will save this to look at some time.
