What a datagrid "sees"

[Bob Sneidar]

Okay I have figured out what this is. the mouseControl is sometimes returning the LAST object that was being pointed to, and NOT the CURRENT object being pointed to. I think this is a bug. I will try to come up with a sample stack and post it on QC.

I can point at another field and this time it might work. Or not. I am not sure why that is happening. It's as though the mouseControl is not getting updated properly. Here is the handler:
