Winfried, many, many thanks for this update. Otherwise your bug report might have been lost... Looking back to your original post of Oct 24, I can see that you did a good analysis of what happened and when. This would be very valuable as a source for a potential fix. Your workaround is good for now (although, as you mentioned, with some costs - adding a subwindow), but this bug *should* be fixed eventually. Unfortunately 3.0 is work in progress, and the person who knows best what's going on is Matthias (Matt) who did the change in svn r 9560, as you found out. It looks as if this was an effort to make coordinates in fltk 3 zero- based, as they should be (outside the 1.x compatibility layer), but something went wrong with it... Could you please file a bug report (STR) for FLTK 3.0 with the information you found out, so that we (in this case probably Matthias) can take care of it later. And please attach your demo program together with an appropriate image. This would be very helpful. http://www.fltk.org/str.php Thanks for your efforts.
