1. Fire up kspread and start with an empty document 2. In A1 type 'text' 3. Right click in A1 and select cell layout 4. Click okay on the box the pops up. 'text' is now in a smaller point size.
Odd... This happens because the typeface changes; for some reason the cell editor doesn't find the helvetica font (but a bogus "helvetic" font instead). Submitting to bugs.kde.org.
