Bug report

Bug description:

My IDLE is set to the default 4-space indent. When I switch to using tabs through whatever the keyboard for toggle-tabs, after the popup message, the tab key generates the tab character.

If I switch back to using spaces using the same keyboard shortcut, I find that the tab key generates eight spaces instead of the usual four. I don’t think that’s the intended behaviour.

This is fixed after restarting IDLE.
