You can find a description of the use of the FMEM program from its author here: FMEM description.

The main side effect to be aware of is that running this program will leave a rather large string object named "JUNK" in port 0. You can purge it quite easily simply by executing:

Code:

:0:JUNK PURGE

[Edit: additional info] Note that purging this object cancels the benefit of the program. So the basic concept is leave the object in place so long as you don't need the memory, but delete it if you need the memory for something else. You can always run it again after you've taken care of whatever needed the additional memory.

The "busy bug" doesn't inherently cause double keypresses, but many users understandably think that their initial keypress wasn't registered and as such will press the key again... which then causes both to be processed.
