Initialization block executes unexpectedly and frequently

I have inherited a masked subsystem with a lengthly initialization block. For some reason the initialization code executes frequently and not always when I would expect. Here are some of the events that trigger the initialization code to run:
- when the next-level model window gets focus
- when I move the subsystem block in the next-level model window
- when I look under the mask
Any ideas why this would happen? It doesn't happen with subsystems I create and mask myself. They run their initialization blocks at times I would expect, like after I change mask parameters.
I cannot upload this proprietary model to a file-sharing site and I have not successfully reproduced the problem in a non-proprietary model, as discussed above.
I'm using R2010b and I don't know what version the masked subsystem was created in, but it was probably recent.
Thanks, Matt

So you have a masked subsystem block. What do you mean when you say "with a lengthly initialization block"?
Every block could have many callbacks. For your masked subsystem block or any of the blocks inside that subsystem, right click a block, select "Block Properties ...", then select the "Callbacks" tab, do you see any callback function?
The behavior you described sounds like the function callbacks are triggered based on various event.
