i have built a winForm wich has buttons, textBoxs fields and a calendar control.
when i click one of the buttons another winForm opens on the first winForm.
now the problem is when i close this last winForm : - all the controls on the
first winForm that where under the last winForm (like the buttons and the calendar)
are being repainted, but there is a kind of delay and for some microseconds i can
see on those controls some leftovers from the last winFrom.
how can i cancel this sluggish control repaint ?
