It's a timing-based issue. So that NetSurf can do work when busy, it will
only poll the Wimp every N centiseconds (wnere N is some number I can't
recall ottomh -- see gui_multitask in riscos/gui.c for the "do we poll the
Wimp this time" logic). Removing this logic results in the thing working
fine. There is utterly no good explanation for this being the case.
Therefore, I'm utterly unwilling to remove this logic. Not least as it
will make NetSurf significantly less performant in every other situation.
Did you try changing the value of N by a small amount?
You miss the point. Changing N to some other value is just the same hack
as removing N entirely. It is not a solution, particularly as the
underlying cause of the issue is entirely unknown. I suspect some kind of
deadlock in the internet stack, but have not had time, or indeed the
inclination, to investigate further.
As I've pointed out on every other occasion that this issue has been
discussed, I've already expended a huge amount of my time and energy on
it and will not spend any more time on it.
