Change the default Correct/Incorrect Prompts

Hi,

Have browsed the discussions dB but can find no mention of how to replace the default Grey frames used for the Incorrect prompts which are automatically created when you record a 'Try out' Simulation.

When I say the terrible output I wasnt too concerned as I expected to be able to 'Globally' change the defaults but I can't even figure out how to change them one by one.   The text boxes can be edited via the design/format tab, but this tab disappears as soon as you try to click the grey frame!

Surely there must be a way to modify these in size/design and colour?
