Input box error message, no recovery
Apologies for my frequent appearance here.
I seem to have a bug in this file that I can't find.
This applet works fine until the input box gives the 'check your input' error message; for example, typing in '10 +' and not completing the addition. Then the input box does not seem to link any further input to the function as I'm expecting it to.
My best idea is to remake the whole applet but I'd like to avoid that.
