1. The display I am talking about is when you are e.g. in a FLAG AREA 
function.  There is a display at that time only which replaces the menu 
and shows the time and flux/phase of the cursor and should show the 
source name.

2. Flagging a time range can encompass 100's of sources if the time 
range does even if those sources were not loaded into the work space of 
the current EDITR execution.  Basically, ALL SORC sets the source number 
to 0 in the resulting flags so that any source within the time range of 
that flag will be deleted.  If your time ranges are all short - smaller 
than or = a scan - then this does not matter.

Flag above will kill points from any sources which are displayed.  In 
that case each flag command in the resulting FG table has a very short 
time range so the all source flag is not important.  Note that the all 
IF and all polarization things would matter if you had more than one.

I will try to see if I can repeat your problem here - although other 
members of the group said that they have not seen it this year.
