Flash menu problems

Have mercy on me, I tried making a flash popup menu which workds all well and good… on its own: subenu appears on cursor over, disappears on cursor out, lovely. BUT if i put two or more together as in a nav menu, every time i move the mouse cursor into the next one, the previous one wont disappear, or somwetimes will, depending on where and how fast the cursor moves over them. Im completely stumped, as it works fine, just not when any menu elements are touching in any way. ill posted the flash mx 2004 file.
