Yeup .. flash player has limits for number of actions executed, so that it
doesn't get bogged down in potentially infinite loops etc.

I thought that might be what it was, as you had the same code in multiple
frames.

In that case, you may get better speed by simply increasing the movie frame
rate.

Also, you might look at using setInterval to do your processing, then you
can call your code faster than the frame rate.

When compiled, a case is the same as an if (for SWF files) .. unlike
compiling 'C' etc to assembly/machine langauge where case statements can be
turned into jump tables etc. There is only a slight benefit from it only
having to calcaulte the expression you're 'switch'ing on once .. but a
switch/case won't be any faster than the old code that used a single if (it
may indeed be slower) .. but it should work better :)

Aha .. what I'd just suggested above too :)
