I'm using the 'select features' (clicking with the select features by rectangle option) tool in ArcGIS 10, and when multiple features are present, instead of selecting them all, one feature is selected, and this little toolbar/icon/drop-down menu thing shows up (looks like a 'switch selection' icon) and lists the other items that should have been selected. I'm sure there are plenty of instances where this would be useful, but almost exclusively, I find it unhelpful at best.
Is there a way to turn this off? (Or a name for the menu/tool object to better search for a solution? I looked at the selection options and general options and found nothing. The ArcGIS help on the select tool doesn't make any reference to it, and I don't know what it's called to find any reference to it.
