In case the key which is pressed after the xterm is resized returns the event immediately to libyui KEY_RESIZE got lost. I will check whether libncurses5.7 from 11.3 has correct behaviour. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

OK this little view.c is not threaded. This leads at least to the guess that this problem occurs in threaded ncurses programs only. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Only the next key stroke does this wakeup and cause trouble due the used fifo -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It could be done also by a configure option or as cpp macro on the command line of the compiler its self. The idea is simply to be able to interrupt the read(2) system call of the reading thread, otherwise this thread will never be interrupted by SIGWINCH as long an other (main) thread is fetching the signal. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
