as far as i'm aware of.. those wall-wart transformer are really not accurate as we can wish. 7Volt can also be 10-15 volt. BUT measure it with a scope to see what's happen when you load it with your PIC stuff. LOOK what the voltage looks like before going to your voltage regulator? A bigger capacitor at the input Help?
You can be surprise... a LDO is a good option btw.
Or choosing another Wall-wart voltage 9Volt and up

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.
