Absolutely no idea - it seems to be in the guts of the X code. I read all
the manuals and put breakpoints everywhere, but I just don't know what the
error is indicating.
what you need to do is recompile the Xt sources with debug info, and find the
place in the sources where this error is being issued, and set a breakpoint
there. this shouldn't be hard, although perhaps a bit time-consuming if the Xt
sources don't recompile easily.
the message indicates that XtRemoveGrab was called on a widget without an
associated earlier XtAddGrab call. those calls are used to create menus and
modal dialog boxes -- anything that temporarily locks out input to all other
widgets.
andy, what state is the focus-handling in your code in?
