Excel 2000 ... Spread sheet is 30 Cols by 5000 rows ...
Only 2 columns with simple formulas, but I do have several
columns with conditional formatting formulas.

Above said ... when I use a Column Filter Switch the
colapses like a clam ... (perfect)

Issue is ... when I use the Filter Switch "ALL" to open
the spread sheet back up ... the rows open as a clam as
well (takes a while) ... spread sheet appears to churn in
calculation mode (message from lower left of screen)

Any thoughts on how to improve this??? ... Thanks ... Kha
