Unbelievable - never believe what people tell you about Tk without checking
for youself!

I just discovered that Tk's Text widget is just fine! IDLE's configHandler
wasn't bothering to update the cursor color. I just added 3 lines of code,
and -voila-! it works.

I'll upload a patch to SF in a bit, but for those of you who want to try it
out, copy/paste this into configDialog.py:

    def ActivateConfigChanges(self):
        "Dynamically apply configuration changes"
        winInstances=self.parent.instance_dict.keys()
        theme = idleConf.CurrentTheme()
        cursor_color = idleConf.GetHighlight(theme, 'cursor', fgBg='fg')
        for instance in winInstances:
            instance.ResetColorizer()
            instance.ResetFont()
            instance.set_notabs_indentwidth()
            instance.ApplyKeybindings()
            instance.reset_help_menu_entries()
            instance.text.configure(insertbackground=cursor_color)
