OK
I've got columns A -AB populated across, and down rows 1 - 9724.
If I press ctrl/end I end up in row 9724 column AD for some reason.
I have repeatedly tried deleting columns AC and AD, and that doesn't help -
but if the machine thinks that's where the end of the sheet is then
something is wrong, to my way of thinking at least.
The problem comes when I try to do a sort on one column (which contains just
letters, no numbers).
I highlight the whole sheet, then Data, Sort, My list has header row, select
the correct column and click OK.
The blue progress bar zooms across the screen and then stops just before the
end, and nothing happens.
I have left it alone for up to 10 minutes to see if it is a time thing, but
eventually I have to resort to ctrl/alt/del to see: Microsoft Excel
StarterPack (Not Responding).
Selecting End Task is the only way out.
I have larger workbooks which sort with no problem, so it can't be a memory
thing.
But what it is has got me stuck.
Does that help you figure it out?
