Variable transfers Between Stacks and Sub-Stacks.

[Simon HARPER]

Hi there,

So I've a main stack and sub-stack for preferences. I save and load  
the variables as a stack (not text of xml - just yet) when I open and  
close the substack. However, is there best practice for how to load  
the variables on startup of the mainstack and then use them in the  
mainstack - refereshing if people change the preferences (in the sub- 
stack) while the application is running?

I'm sure this must be done a lot but I wonder if there is an accepted  
best way. Also, would I just define a global variable for inter-stack  
variables?

Cheers
Si.
