xemacs 21.2-b42 on Alpha Linux problem

Hi, I've just compiled xemacs 21.2-b42 from today's CVS on an Alpha Linux system, and it worked even without pdump. Great! Only there's a little problem: Each time I move the mouse in the tiny gap between the topmost buffer line and the tool bar, I get this message: Domain for this instantiator must be resolvable to a window: [autodetect :data "xterm"], #<x-frame "emacs" 0x1f5e> This is somewhat irritating, since xemacs blinks for each pixel the mouse gets moved... Could anybody give me a hint what to do?
