xemacs lies to my window manager

i use gwm, afaict a good behavioured window manager, maybe a little picky in its interaction with applications... some times ago, i complained that the 1st frame that XEmacs mapped to the display had to be remapped by the window manager to got the right dimensions (definition of right: i use my wm to have appropriately sized and properly stacked XEmacs frames) now the situation has gotten worse XEmacs now *lies* to the window manager, that now is unable to get the window to the right size when remapping it, and is addirittura, what's the english word... well, if i resize explicitly the 1st frame using the mouse, there is a discrepancy between the meter displayed by the window manager and the actual size of the window all the subsequent windows are _normal_, and the only cure i devised is killing the 1st frame (rather inelegant, though) ciao ps: what about the bold/italic face bug???
