Hi Judith,
I'm glad that I got see this even if it wasn't meant for the list.

I'll try to duplicate the Destroyed Handle situation. This message occurs
when a widget that has been destroyed is referenced after the destrucion. I
noticed that this was a problem with some internal assuptions in v0.53 and
addressed those, so maybe I've fixed your instance as well.

Unfortunately, Microsoft in their wisdom, have decided that STATIC controls
do need to see input events, such as mouse clicks or keyboard presses. There
are meant purely as adornments to a window and not meant to be
"interactive". In order to get around this in my programs, I've used
borderless Windows instead. This has other side-effects but it does the
trick.

On the other hand, I've used LText controls with WS_EX_CLIENTEDGE to make
them look like normal edit fields that are "disabled".
