fix initial height of multiline input window

There is a hardcoded preferred height for the input window that was getting picked up becuase the result of GetTextHeight was just '1' ( due to no font being set up ) We shouldn't use a hardcoded value, we should always use the proper text height e.g. the result of a successfull call to  GetTextHeight() ( the patch makes sure we get a decent result from this call )
