Memory Guardian and CFP memory usage

Does anyone know why my memory usage for CFP drops to 5,500k from its usual 15,500k when I have CMG installed?

Is this a bug or is it expected behavior?

Just noticed that the reduced CFP memory usage only occurred after initial installation of CMG and first re-boot.
After second re-boot the memory usage is back to normal.

Still, quite interesting. Does this mean that there is a problem after initial installation?

Did the CFP GUI happened to be opened and then minimized?

No, afraid not. I have removed CMG again now due to the BOClean problem but I will try it again later and make a note of everything that happened.
