Why my CViews lose their drawings when moving upward?

[rbarella]

My CViews are created with the style WS_CHILD | WS_VISIBLE |WS_CLIPSIBLINGS |WS_TABSTOP.

When the whole MDI is dragged up, toward the top of the screen, they lose some of their drawing (forms and lines), but NOT the writing.

I have somehow fixed up this problem setting a timer every 60 milliseconds, which invalidates the window if its top is lower than before.

Could anybody suggest a less clumsy solution?

Thanks.

it is because messaeg WM_PAINT is a message with low priority.
