Hi,

when calling endwin()/doupdate() more than once and if the screen contents changes between these two calls, the screen is not correctly preserved/restored during the next call to endwin().
I have checked this with cygwin (15.25) and PDC 3.3/win32
I have set the environment variables
PDC_PRESERVE_SCREEN=1
PDC_RESTORE_SCREEN=1

I have made a patch (win32/pdcscrn.c and refresh.c) that solves the problem for me (see attachment) - however, I'm not sure about the correctness (by means of SP validity) of the patch in pdcscrn.c

You can reach me "vco (at) gmx dot net" for further questions.

Best regards
Vassili
