Why not ? Is this design issue, or implementation one ?  I think the actual
widget instatiation is done by FetchWidget which takes a parent widget.  Is
it impossible to resolve resources by this parent's display ?

Fortunately, I don't. (I'm not a hacker ;-)

Does this feature(not bug) of resource manager apply to following problem ?   

"BadFont" error occurs even in case of single UIL/toplevel application when
widgets are instatiated second time after closing old display and  opening new
display.  

Anyway, I believe these two issues are common among UIL user.  Are there any
alternatives or future plan to meet our requirements ?  Or should I convert my
UIL objects (~100) to C code ?
