Hi Adam,

The issue was caused by the following code in GNUMail:

  aSize = [[NSFont seenMessageFont] maximumAdvancement];
  [dataView setRowHeight: aSize.height];

The height is always equal to zero when using the winlib/win32 
backend. This code is used to adjust the height of the table view rows 
based on which font is being used.
