[MlMt] strange behavior when selecting multiple source accounts

[Eric Sharakan]

Hi, since I can't access several of my email accounts when connected to 
my corporate VPN, I select the impacted source accounts, right-click 
(via a two-finger click of my MBP trackpad) to bring up the contextual 
menu, and select "Take Offline" or "Take Online" as appropriate.

Often, after selecting the set of sources to take offline or online, the 
two-finger click to bring up the contextual menu acts as a normal 
left-click, changing the selection to only highlight the source my mouse 
pointer happens to be hovering over.  This most often happens if I move 
the pointer after I select the set of sources but before I do the 
two-finger click.  If I'm careful not to move my pointer, I almost never 
see this behavior.

This only seems to happen when selecting multiple source accounts; I 
never see this problem anyplace else I select multiple items and invoke 
a contextual menu.

Any thoughts?

Thanks.
