I'm trying a couple of things on it now (shortening the cable run from the outlet to the cable-modem and running the network cable straight to the router rather than through a surge suppressor. It's not that high risk a spot for a lightning strike so maybe just shortening up those runs will be all I need.) So IF that improves things then I might be available this evening to start accepting invites again. I'll try to do some testing during the day today and let everyone know.
EDIT: Oh, and Honey Bee, only what you tell to get saved on your SD card is saved there. I think with the last upgrade you can force more stuff to move to the SD card, though, so you can save even more there than you may have had before (like startup stubs and such that should help programs to start faster than if you were running from the CD directly.) But if all of your saves are on the SD card you've got all the important stuff there anyway so you should be good.
PK, I forgot to mention when you gave us the listing of upcoming Wii songs that some of us really only read this thread here, so I think it's awesome when you post the lists here! (Well, OK, maybe not ONLY this thread but mostly only this thread.)
