filepaths for multiple builds

[Edward Cawley]

Hi all
I'm trying to build standalones for mac and windows and I have a 
problem.
I am developing in MacOSX.
I have a large number of images which I access by filepaths. I don't 
need to specify the hard drive in MacOSX just the file name on the hard 
drive (/river?).but when I access them in OS8&9 I need to indicate the 
hard drive name (ie /Macinosh/.......as well. I'm not sure what I need 
to do for Windows? I can see that I could use an if then to change the 
filepaths to fit the operating systems. But how can I find out the 
operating systems for the scripts?

A second question is an odd behavior I see when I change the image by 
changing the source filename. Sometimes there is a blank area which 
isn't drawn, not the whole image but just the bottom 10%. If I go to 
another card and return the image is complete. It isn't a empty field 
or any other object. No big deal, but it is a puzzle. Any ideas?
Thanks
Ed
