Invisible or virtual users? What's going on?

Hi, I just took this screen shot from Vugraph. There are less users listed than the number of viewers at the top. Also there is a empty piece of list at the end which corresponds to the "missing" viewers.

 

What is going on here?

Correct. For obvious reasons 3 of my 4 accounts will always be invisible during vugraph broadcasts (Walddk2 gets plenty of private messages as it is). So I have probably been there. I count as a spectator but you can't see me.

Any invisible yellow can kibitz at any table and not be seen (except by other yellows at that table).

 

It used to be the case that any invisible non-yellow kibitzer at any table would become visible to everyone at that table. About a year ago I made a change so that non-yellows could retain their invisibility when kibitzing at vugraph tables.

 

Drawing a list of kibitzers involves the following steps:

 

1) figuring out the size of the background rectangle

2) drawing the background rectangle on the screen

3) drawing the line in the top left that displays the # of kibitzers

4) drawing the names of visible kibitzers

5) drawing the scroll arrows if appropriate

 

The BBO client knows how many kibitzers are at the table, but it does not keep track of how many of these are visible. To do 1) properly, the client would have to either keep track of this information or figure it out at the time in which the user moves his mouse over the top left part of the table.

 

Neither solution would be particularly difficult for me to implement, but given that almost all vugraph broadcasts almost always have enough visible kibitzers to make the rectangle at least one full column in size, the condition described in this thread is not very common. Besides that, it is not exactly what I would call a serious problem :)

 

So know you know what is going on here.
