I need to finish a pfSequence CYCLE with the last data set in the cycle
displayed permanently.
There seems to be ( that should be the performer motto :-) ) a "feature"
that causes a one frame glitch. If I check to see where I am in the cycle
each frame and trap the last child changing the mode from CYCLE to
Sure I get the fixed "image" but first there is a 1 frame time period when
nothing is displayed. This happens even if I try to trap the 2nd last child.
ie it seems that calling PFSEQ_START gives a delayed action in the meantime
displaying no children.
This is frustrating - am I perhaps doing something wrong? Any ideas? I seem
to have temporarily solved the problem by trapping the last child and executing
a PFSEQ_PAUSE. (Interestingly if I then wait a few (one ?) frames and THEN call
PFSEQ_START there is no problem, the changeover is seamless.

BTW. I needed to change a menu button's contents whilst performer was running
so I added a pfu function that allows menus to be changed - if anyone
is interested.
