2885.0. "XLowerWindow to the DECterm window...." by EWBV37::HIME (I hate you FORTRAN) Wed Jun 06 1990 05:32

	
	A question about XlowerWindow on DECterm window.

	Using following program, XRaiseWindow does work fine 
	but XLowerWindow does'nt.  Is there any differrence 
	between Raise and Lower?

	Anybody Anyhelp?

}

XLowerWindow on a shell window appears to be a no-op due to a bug (?) in
the XUI window manager.  As far as I know, no workaround has been found.
