Without any attempt to analysis (yet), I really cannot see what stat file handling, and access to disk in general, should have to do with semaphores? > MSEgui has custom methods to access disk that does not work on aarch64. These custom methods must be rather, arrr, idiosyncratic, then.

I do remember that there were problems with the freely definable (integer) field of components during the transition from 32 to 64 bit capability. Martin had to enlarge the field that was sized 32 bits wide initially to accomodate the occasional use for storing arbitrary pointers. If in the aarch64 architecture there is a similar change in field size, it might well cause an occasional overflow or invalid memory access and make a program crash or behave unintended. > About the problem of colormask, of course your fixes are more than > welcome. Well, there is no fix (yet, I hope). I'm afraid you will need quite some patience. -- -- (Weitergabe von Adressdaten, Telefonnummern u.ä. ohne Zustimmung nicht gestattet, ebenso Zusendung von Werbung oder ähnlichem) ----------------------------------------------------------- Mit freundlichen Grüßen, S.
