[Bug 3637] dialog: no wm_paint message at first draw

https://bugs.winehq.org/show_bug.cgi?id=3637

--- Comment #18 from Alexey Slepov  ---
As it is described before, it's about WM_PAINT event.
On choosing in menu "Help"->"Periodic Table" in that "Periodic Table" window
there must be shown a color box under "Selection: C".
You can see the color box when you click on any chemical element (because of
repaint). But it must be shown at the very beginning.
The bug is there in wine 1.7.44, I don't know about 1.7.45.
