UI performance and large data set in Table Object

[mfstuart]

Hi Richard,
I did as you suggested and copied 8 columns of data (20,844 lines) into this
new stack.
Just a table object on the card - no scripts (except your 'on resizeStack'
in the stack), no other objects.
resize result: same slow behavior :(

Any other thoughts on that?
