[BUG, minor] display garbled when resizing window while copying files

[<tux centrum cz>]

When I start to copy files and resize the terminal window while the copy progress dialog is displayed, the display become garbled - dialog is moved, but the values (percentages, kb/s information, etc ...) are written somewhere else (outside the dialog).
It's minor bug, since when the copy finishes, mc restores to normal (and  resizes itself to terminal dimensions)
