>Actually I have tried it both ways. I even tried locking the screen until I was done. Can figure this one out.

I have a grid class that does this - just looked at it. Here is how the code works from a page Activate:

grid.activatecell()
grid.setfocus
grid.activatecell()

Looks funny (interaction between pages & grids is a little peculiar), but this works for me.
