Spreadsheet Format > Conditional formatting 'Add' has the focus, is OK Enter to add Now you can't get the focus to the upper part, with the conditions. Use mouse to go there, e.g. the field to enter a value use Tab to go to next field... Again does not work: focus jumps to lower part of dialog.
REgressions only are in old code. New features and new dialogs don't have regressions. Also please reuse your existing bug report and don't open new ones.
Argh - sorry Markus. (I really should stop trying to do some extra work in a rush ) *** This bug has been marked as a duplicate of bug 51556 ***
