Moving between fields in HyperCard 2.0 is quite slow. It is especially slow if
you have a large number of fields on a background. To improve this performance,
you have two basic options

1) Your best shot is to try to reduce the number of fields on your background.

2) Rumor has it that resizing the System Heap will help with this problem. I
have not tried this myself, but it came from a good source (Kevin Calhoun @
Apple) so I tend to trust it. I am sure however that this gain would be marginal
at best.
