Minimising a window ignores minsize

[JkWhoSaysNi]

I've created a gui window... (Attachment 1). It looks great in game... until you minimise it (attachment 2).

I have set the minsize attribute on the window so it cant be dragged smaller than it should be but minimising the window ignores this value (and the size of the graphics).

Anyone know how i can fix this?

I think the only way to fix it would be to set a different window graphic when it's minimised and then reset it when it's maximised but if anyone can think of a better solution I'd really like to hear it.
