Hi!
In analysis window the multi-pv spinbox is grayed for xboard
engines and uci engines that do not allow for multi-pv.
However, once you pause the engine it is set to active and
stays active. (It does no harm to the engine as far as I can
see as the engine seems to just throw an error and ignore
the multipv settings it can't handle.)
Additinally, I found some "inconvenience". Most engines
actually restart their calcluation right from the beginning
if they get paused. This seems to be an engine bug,
actually. Shredder e.g. works as expected and just continues
where it left off, but I found the "wrong" behaviour in all
my free engines. Therefore, it is not advisable to halt
e.g. Toga to copy the current analysis to clipboard. However
the lines might change to fast to be able to copy it without
pausing the engine. :(
A possible solution to this probelm is maybe to stop
analysis update once the user starts to mark text in the
analysis output (button-1-press) and copy it to the
clipboard automagically on button-1-release and restarting
the update procedure again. This would be how it should work
on X11 anyway, but the refreshes are to fast, that is it
doesn't even work there.
