This is not an HP specific problem. In fact, if you want to complain,
talk to the people at DEC's Western Research Lab who designed and wrote
the stuff. Make sure to ask them how they like programming in C. If you've
ever delved into the Xtk internals you'd go gaack! Try profiling a widget
program and see how many times malloc and free get called.

Help is sort of on the way in the form of gadgets (windowless widgets). Other
people listening may have specific suggestions for you, but it sounds like
you've already discovered the manage/unmanage trick.

As far as other problems, post away. I can't guarantee that I or anyone else
will be able to answer them, but it can't hurt *as long as you are also
pursuing them through the normal channels*.
