after thinking about an answer for a short while, someone else might have given their answer, so if you "refresh"the page ( a round arrow sign somewhere on your toolbar) you can see if anyone else has answered in the meantime
Hi Bob,
The screen does not "refresh" (update) itself automatically, so you have to click F5 key or click on "forum" to see the latest post. I sometimes forget to do this, and so am a bit behind in seeing others' posts.
