overlapping windows in pdcurses/ncurses

I need help with my first program, which is using an additional library: pdcurses (ncurses). I created the pop-up window and it works. The problem is when I try to delete this window. As you might guess, though I deleted it, the blank spaces are still there. At first I thought that it wasn't a big deal, I could just recreate the background (another window) again. Nothing could be further from the truth. When I'm recreating the windows using create_rightwin(col, row);, create_leftwin(col, row); again, it breaks this part of these windows, which haven't any contact with the pop-up window. It looks like attron is on, and all titles in other windows are reserved. I've read in the internet that I should use wintouch(), but I don't have any idea how and when to do it. Did anyone have any similar problem?

As noted, the panel library solves problems of painting and updating overlapping windows. Both pdcurses and ncurses provide a panel library.

The ncurses programming how-to has a section on the panel library (which includes an example):

The how-to originally came with a zip-file with the sources, which seems to have been mislaid. There is a copy of that linked in the ncurses FAQ in a section listing the how-to along with some other reference material.

The ncurses sources include several test-programs (not as simple as the how-to); a few of these demonstrate the use of panel. Those test-programs are separately available as ncurses-examples.

The panel library is also supported in a few bindings from other languages than C, as discussed in these pages:
