You have something very fundamentally wrong. This is not expected or
correct behavior for XForms.
I just banged together a little test program which displays and hides
a window with four input objects in it. The inputs stay around (as
they should) and there's no problem with any X errors being generated.
Try building that and see if you still have problems. If you do, then
I suspect you have some error in your XForms installation -- say
library skew or library incompatibility (libc vs libforms, for instance).
