Re: [wmx] sluggish netscape with channels

Joel Reicher - Wed Jan 26 01:23:38 2000

FWIW, I experienced this as well and I think it's related to the focus
problem I mentioned a few weeks ago, because if focus was brought back to
the netscape window `explicitly' by clicking on wmx's frame for the window,
the problem went away.
