Is it possible that it has something to do with setting/clearing the cursor? I
remember vaguely that there was a similar problem with the CBMs. If the
runtime thinks a cursor is displayed somewhere it will try to switch it off.
If the cursor position is not correct, or other screen related variables are
messed up, this will lead to strange results, like the one described.

In general I would say that using conio together with direct screen or
variable access, or together with ROM functions is not supposed to work. At
least with the CBMs all sort of weird things may happen.
