This might just be a font issue. Can you take a screenshot to show us what
it looks like? Have you changed the font settings?

(not to answer) / becomes YEN symbol in IDLE editor, not in terminal or 
Notepad++

IDLE is based on tkinter is based on tcl/tk. tk handles keystrokes, so 
this is almost certainly a tk and not an IDLE problem. Tk must somehow 
think you have a non-US keyboard.

Save the following to a file and run the file both in IDLE and from 
Command Prompt or Powershell.

from tkinter import *
root = Tk()
text = Text(root)
text.pack()
text.focus_set() # required to work on Windows
root.mainloop()

Type backslashes into tk Text box.

IDLE does not run you code. As far as running code goes, IDLE is an 
input-output front-end run by Python. It displays what Python outputs.
If you had run the same code in Python directly, you would have seen the 
same result.

 >>> num = .1 + .1 + .1 + .1 +.1 +.1 + .1 + .1 + .1
 >>> num
0.8999999999999999
 >>> print(num)
0.9

Interactive echo (>>> num) prints repr(num), which is as accurate as 
possible.  Print prints str(num), which in 2.7 is rounded to a 'nice' 
form.  Because this was confusing, it was changed in 3.0.

 >>> repr(num)
'0.8999999999999999'
 >>> str(num)
'0.9'

Issues of round-off error with floats are well documented.  I believe 
there is an entry in the Python FAQ for this.

Summary: no bug, and nothing to do with IDLE

Thanks for mentioning the OS.  1. and 3. are probably OSX-specific 
problems with tcl/tk.  Did you upgrade from the Apple supplied tcl/tk, 
as recommended on https://www.python.org/download/mac/tcltk/ ?  If you 
have already done that, or if you still have any of these problems after 
doing so, please open an issue at bugs.python.org.

I do not see this with Windows.  Such a gross error, must be OS and 
maybe even version specific.

https://bugs.python.org/issue15786
is about problems with clicking on completion box.  No need to report 
this, but you can add a comment to the issue if you want.

For me, the box disappears, the cursor remains.

This is likely a tcl/tk problem with the OS.  Run Python 3.5 from the 
console/terminal with 'python3 -m idlelib' and you may see an error 
message there after the crash.

In you first image (for 3.2.3) you have the editor window active and Run 
appears on the menu bar and Run Module F5 shows on the dropdows.  In the 
second image (for 3.5.0) you have Shell active and Run is not on the 
menu bar.  You have to make an editor window active for Run to appear.

If on Mac OSX, I recommend upgrading tk

Quite visible to me. What happens when you run the interactive 
interpreter directly?  What happens is you click Options / Configure 
IDLE / Font tab, and change the font?

When this has come up on Stackoverflow, the answer has been that the 
person is using a *nix system, such as Mac OSX, has 2.7 installed with 
the system, and separately has installed 3.4.  They download and install 
xyz for 3.4, run 3.4, type 'import xyz', and it works.  Then they run 
'IDLE', but it turns out that they are running IDLE with 2.7, not 3.4, 
and xyz is not installed for 2.7.  I suspect something like this applies 
to your case.

No.  The license comes with Python.  In the interactive shell, or IDLE 
Shell, type 'license()', as the splash message says.  But the license is 
about redistributing Python or derivatives. If you are not doing that 
(and programs written in Python are not derivatives of Python), just run 
Python/IDLE and enjoy.

it is hard to remember to do that.
