Re: Xarea weirdness

Hi Fer,

I tried the gui and its not behaving as you say on my system (Win 7). The
background remains blue all the time.

The only case when a white rectangle appeared was when I tried changing
various parameters through the windows display interface. I changed "clear
text", etc just to try out to see if something like that was the problem,
and then when I brought the gui to the front the rectangle was visible. As
soon as I moved it off screen and then back again though (to cause it to
redraw) it was blue again and remained like that whatever I did (resizing
etc).

I can't see that there's anything I can do...

xArea is a BS_OWNERDRAW type gadget with the WS_EX_TRANSPARENT exStyle

This means that windows leaves it up to me to draw what I want and since I
have declared it as transparent, I shouldn't have to do anything.

It happens probably because MS changed the visual updating routines to make
it faster and more efficient. There's quite a few little things like that
I've noticed. I don't know yet how to fix it though.
