	I have a (hopefully) quick question about matrices, cells and  
tags.  I use browsers in several places to allow the user to select some  
entity.  When I load the matrices, I set the cells tags to unique values  
so that I can easily identify a selected cell.  Well, I can get the cell  
that is being selected, but it's tag always returns as -1.  I'm having to  
identify cell by their stringValues, which is very inconvenient.  Does  
anyone have any ideas why I might be getting the behavious I am?

	As a quick update to those familiar with my plight... the  
prototype is going pretty well.  I have the majority of the general  
structure of my program together.  (Things are not being done nearly as  
neatly as I would like... I plan to clean it up when the rush is over.   
Actually, sleep will come first...)  Much is being handled by external  
programs.  I am using Speaker/Listener to have ImageViewer open TIFF  
images and to have Adobe Illustrator open converted AutoCAD files.  (I'm  
pre-loading the Illustrator files for performance reasons; can't do that  
with ImageViewer as it's not smart enough to know when it already has a  
file open.  Fortunately, the load time on the TIFFS is acceptable.)  I'm  
using distributed "I can't believe they're that trivial to implement"  
objects to control Movie.  (That is just so amazingly cool!  NeXT, you  
outdid yourself this time.  Now I hope everyone starts setting up server  
objects and supplying the header files for them.)  GETTING the video has  
turned out to be more of a problem than I expected... the images we grab  
on the pc don't look that great, but that's all we've got to grab them on.  
I've created a boatload of screens; probably 3/4 of the screens are done.   
I've stolen icons from all over the system.  I haven't done any database  
stuff at a programmatic level (though the interface level works great); I  
may not have time to learn how to do that, in which case all my data will  
be dummied up.  I've learned a good bit... enough to motivate me to keep  
going after the demo!  The demo, by the way, is next Wednesday, but I have  
to have this wrapped up early Tuesday morning.  I will be posting to let  
everyone know how it went.  I am at an additional disadvantage in that  
this stuff will be in amongst a bunch of actual products on other  
platforms.  My stuff already looks cooler than any of the other stuff.   
That could be largely due to the way cool icons I snarfed...

	I appreciate everyone's help; I will be acknowledging all messages  
when I get a opportunity to breathe.  For now, back to work.
