Hi,

I just noticed after doing a bit of experimenting, that Calc had not changed 
the height of cells back to the normal height when returning the scale back to 
100% from 200%.

To reproduce:

Open Writer
Select New -> Spreadsheet
Select Tools -> Options -> OpenOffice.org -> View
Change Scale to 200%
Close the spreadsheet

In Writer
Select Tools -> Options -> OpenOffice.org -> View
Change Scale to 100%

Now
Select New -> Spreadsheet

The cells have not reverted to their normal 100% size, whilst everything else 
has.

To get everything back to normal size whilst in the spreadsheet change the 
scale to 200% (or probably anything) and then change back to 100%.

Hope this helps

Kelvin
