Pidgin Invisibility Option

[Benjamin Mark]

Good evening,
Example: I log in at 10PM. I go invisible at 10:30PM. I re-emerge at 11PM. The 
thing of it is this: The viewer at the other end who sees me at 11:05PM in my 
visibilty state has but to mouse-over my name to see that I have actually been on 
line for over one hour as opposed to only 5 minutes. This defeats in some degree 
the invisiblity factor unless I exit first and then come back as behing visible. Is there 
a fix for this?
Sincerely,
Benjamin
