Emu XL-7 & MP-7 User's Group

Hey gang,
Just last night, UPS delivered my Protozoa ROM and my Protean Drums 
ROM. Needless to say, I installed them right away into my XL-7. The 
ROM slots now hold (from first slot to last) the XL-7 ROM, the Pure 
Phatt ROM, the Protozoa ROM, and the Protean Drums ROM. I've noticed 
something strange, though. I assumed that when using the Sound 
Navigator to select which ROM I wanted to work with, that they would 
appear in the order I installed them: XL-7, Pure Phatt, Protozoa, 
Drums. But they don't. They appear XL-7, Protozoa, Pure Phatt, Drums. 
All of the presets seem to work okay, so I don't think it's much of a 
problem, but I'm hoping that there's not something wrong with my XL-
7. Is this a normal thing to have happen when installing new ROMs? 
I'm probably just worrying for nothing, but I waited six months to 
get my XL-7, and after packing it with ROMS, I've spent a small 
fortune - by my standards!:) Anyone else encounter this?

p.s. I just recently upgraded to OS 2.0. Would that have anything to 
do with it?
