Indeed. This was my message too, Ken. You do not need to poll for 
mouseDown/Up/Release (whichever). They are events, unlike mouseClick 
function, and will be caught between the short pieces of code executed 
by the send-in-time. You do not even need a repeat loop as such. 
Send-in-time can achieve that by sending itself, with local or global 
variables or properties holding the object reference for highlighting, 
and any other state information.
