As you know, Plus! replaces the colour combobox in the standard WLM font dialog, with the 'Enhanced Colour' picker. And when you change the colour, it updates the colour in the sample frame.
But when you manually create your own Font dialog in a script, Plus! detects the creation of it and subclasses it etc and adds the Enhanced colour picker to that as well, which is ok, except it doesn't update the colour of the sample. I know this is probably as it's not WLM that created or whatever, but I think one of two things needs to be done.
[list=1]
[*]Dont add the Enhanced colour picker to font dialogs created from scripts
[*]Add it, but also update the sample colour, as it does when WLM shows the dialog

Hope Patchou reads this and can give some feeback
