When writing a note in the calendar on my Nokia E72, the text in line one disappears, how to fix this?

This issue has been fixed in the Nokia E72 version 071.004. In the fixed version the text is visible all the time.

Note! On Nokia E72 version 054.004 and earlier the text disappears if text is longer than one line, but the whole text will become visible again after exiting the input field.
