Hello.

This question might be somewhat off-topic, but I hope someone can at least point me towards the right direction for solving the problem.

I'm having issues with some applications (mostly games, but also some seemingly native GS/OS applications), in which move the mouse pointer erases whatever is the foreground, sometimes replacing it with black squares (following the mouse pointer, thus causing a wide black stripe on the screen; an example of such application is “Ugly Duckling”), sometimes with white squares/stripes (e.g. ORCA graphical editor), and sometimes with traces of previous screen content (e.g. King's Quest 2).

I tried to swap ROM01 and ROM03, and it didn't seem to do any good.

Of all the applications that I tried, the only one for which I found a workaround was KQ2: when I boot it from floppy, without going through GS/OS, it seemed to work perfectly, both with ROM01 and ROM03.

Is this a known issue, preferably also with a known fix? If so, how can I fix it?

As additional information, those issues happen for me with KEGS 0.91, 1.28 and 1.29. I run them on Linux.

(I am an old not-enhanced IIe user, who's just recently developing interest in retro-computing, having just some months ago resurrected the IIe of my childhood, some 39 years ago, but I have never used a IIgs.)

Thanks for yor attention,
Paulo

More likely a software conflict. Try holding the SHIFT key (is it the shift key that disables loading extensions and desk accessories on startup? Someone can correct me if wrong), on startup to disable extensions and desk accessories. Then try your games again.

Disable CloseView (init), EasyAccess (init), and VideoKeyboard (NDA).
