Re: [MACTCL] MenuButton problem

[Jim I. <ji...@ap...>]

Yes, this is the suggested workaround.  The problem is that we need to make
sure to keep around the GrafPort for a window as long as any of its widgets
might touch it.  There is a ref-counting scheme to try to make sure this
works, but destruction in Tk can be quite contorted, and I haven't had the
time to figure out how to get this case to work properly.  Since there is an
easy workaround, the bug stands.
