[SOLVED] Wrap Text in Merged Cell

[stefan via OfficeKB.com]

Hello,
Ich have a merged cell "C22" which spans over columns C:H in row 22.
Contracry to single cells, when the text wraps, the cell height does not
adjust automatically. Actually, does not even adjust when you click between
the row headers. One has to drag it to fit. Is there a workaround, something
that can be embedded into a Worksheet_Change option or so?
Thank you for your help.
Stefan
