[issue15853] IDLE crashes selecting Preferences menu with OS X ActiveState Tcl/Tk 8.5.12.1

[Kevin Walzer]

Kevin Walzer added the comment:

editFont.config is causing the crash. 

The revised patch you suggest configures both the display font example and the highlight-text example. We can certainly amend my patch along those lines.

I cannot reproduce the issue in simple Tcl/Tk using the equivalent [font create] and [font configure] calls. As noted, bugs involving the Tcl/Tk event loop on the Mac can be hard to reproduce. It is usually simpler, where possible, to work around the issue at the script level.
