<pre>Description:
A spreadsheet with alternating blank rows makes many column and area mark
operations slow.
Steps to Reproduce:
New spreadsheet
Create solid block of A from A1 to N32000
Place "A" in A1. Select A1. Copy to clipboard.
Mark A1:N32000, paste, yes to overwrite. Note the fast paste.
Select each column individually A then B then C.. to N. Note the fast response.
Fast response is expected behavior.
Close all, new spreadsheet.
Create block of A from A1 to N32000 with all even lines blank.
Place "A" in A1, leave A2 blank.
Select A1-A2, copy to clipboard.
Select A1:N32000, paste, yes to overwrite. Note slow paste.
Mark each column as before. Note slow response.
Slow response is unexpected behavior.
Close all, new spreadsheet.
Create solid block of A from A1 to N32000
Change column A so it is blank every other row.
Mark column A is slow. Marking all other columns is fast.
Actual Results:
See above.
Expected Results:
See above.
Reproducible: Always
User Profile Reset: No. It happens on multiple computers.
Additional Info:
This is likely to affect blank every other column but that has not been tested.
