PNGOptimizerMBS.YieldTicks as Integer

dim p as new PNGOptimizerMBS
p.YieldTicks=6 // only use 1/10th of a second

If value is greater than zero, the application will yield to another RB thread after the given number of ticks have passed. 60 ticks are one second. Using a small value can slow down processing a lot while a big value keeps your application not responding to mouse clicks.
If you use this property with e.g. 6 as the value, you may also want to use this method in a thread so you can handle mouse events or let Xojo redraw a progressbar.
