Saving NetConfig in 5.6

We are getting some weird behavior in 5.6 with the saving of the NetConfig and wonder if anyone else is seeing this.  Here is the scenario.

I open a NetConfig that someone else has locked.  I open it up in “read-only” mode.  Then, without thinking, I make some changes and click save.  Of course it tells me that “Hey dummy, you are in read only mode.” So, I close the NetConfig and open it back up.  Lo and behold, my changes that I attempted to make are there.

That’s not normal behavior is it?  

Thanks….
