Mike,
Both of your bit of code are not equal.
On my ISP in 4.0.6 isset returned false if the variable was not existing OR
empty
in 4.2 isset returns true if the variable exists but is empty, so you may
want to check with empty instead of isset

Er, yes! ;)
(I cut-and-pasted one example to create the other, and then changed the wrong "on" to
"off"!!)
