Setting directory on preOpenStack, not seeing images with relative file paths

[Karl Becker]

I am setting the directory (the defaultFolder) to a different path on  
a handler called from preOpenStack; I do this so I can access image  
files that sit in another directory immediately when the stack opens.

However, when the stack opens it sets the directory, but it draws  
everything white at first, like it did not have the directory set.   
When I click to move an image object with a relative filepath,  
though, that image object then draws properly.  The other images do  
not, though, and neither do the backgrounds of graphic objects that  
have their backgroundImage property set to an image residing on the  
card.

Is there a way to force the stack to do reload all the images with  
relative file paths?  Or is there another solution which you can  
think of?  Please ask me to clarify if I have not been clear.  I am  
totally stumped on this problem.

This help will be extremely appreciated, thanks,
Karl
