Any thoughts on speed limitations of Revlet?

Thanks Sarah. Your feed back was very helpful. I confess that when I  
ran the stack I posted to you I got the same results you did--and not  
the same as I obtained earlier when I ran the full stack from which I  
extracted the bit I posted.

Just to isolate the  issue of the graphic display, I tried a very  
simple stack: A single image (my barn last winter) with a MouseMove  
handler.

go url "http://www.jamesphurley.com/MoveGraphicTest.rev"

When I drag this image around the screen (running in Safari from the  
file on my desktop) I found the motion to be rather bumpy, not nearly  
as smooth as when running in desktop RunRev. It is tolerable, but  
bumpy. As you say, this may be something that needs tweaking as the  
plug in evolves.

I haven't tried uploading it to the my web server. Not sure how to  
proceed to the next step. The url in Safari looks like this:

file:///Rev%20apps%20on%20web/Untitled%201/test.html

I never have figured out what character the  %20 is a substitution  
for. Little help? How would I proceed from this Safari rendition to  
posting it to my on-rev web site for a test?

Thanks,

Jim Hurley
