I tried the lshideexplorer trick as well, and interestingly, you're right, the mem usage is about the same. Who'd've thunk explorer would take less than 5 megs of memory to run! (It's actually taking just under five megs at the moment, but for a bit there LS and explorer were taking about 2 a piece.)

But my problem isn't with the tray not updating; instead, some icons appear in my LS tray, while others appear in my explorer tray. (Right now, my Bluetooth software's tray icon is in LS, as well as my Yahoo! messenger icon, but my system's sounds icon and everything else i start with a tray icon is showing up in explorer.)

This is an interesting little problem, I wonder if there's a way around it...
