I recall an interesting thread from last year regarding XMANAGER
internals, and whether you even needed XMANAGER to run a widget program.
A search on Google Groups

http://groups.google.com/groups?group=comp.lang.idl-pvwave

for XMANAGER yielded the thread "Re: Xmanager R US" as the first hit. In
the thread, Pavel Romashkin and J.D. Smith make some interesting
observations about the workings of XMANAGER which may be relevant.

Cheers,
Liam.
