[R] speedier rendering

[janet rosenbaum]

Hi.  

We've written a GUI for R.  Under linux and Macintosh, it looks good, but 
under Windows, the rendering is unbearably slow.  
Can we do anything to speed it up?  
Is it possible to compile our program, for instance?

If not, I have a second question:
The buttons on our GUI move over whenever an operation is done, and 
that is what makes the rendering visible.  The buttons only move under
Windows, though.  On Mac and Linux, they don't move at all.
Has anyone else experienced this?
Is it possible to make the buttons stay put?  

Thanks so much,

Janet
