Having an issue, seems to have started immediately after I took the Wii online and did a few things like check Gmail and Vgcats.com.
When I try to shut off the Wii with the 'motes power button, the music in the Wii menu stops, the pointer disappears, but the machine remains on. If I press A or something, the 'mote resyncs, but the music doesn't come back. If I go into other menus or channels, it remains silent.
At first I thought "this is because my 'mote was synced as the second one." But I tried the other one I have and the same thing happens.
I could only turn off the Wii by physically holding the power switch on the system itself for several seconds - maybe 6-8 or so. It would then go red (WC24 off). If I turn it on with either the switch or the controller, I'll get the same issue when I try to turn it off. This issue also occurs if I try to shut off directly with the power switch.
In short, no matter how I try to turn it off, the only way to do so is to hold the power switch.
I tried to unplug it, but this did not help. Basically it looks like I cannot get back onto WC24 during idle time. I have made sure my system still shows WC24 as automatically connecting during downtime.
This OS is very buggy and it is starting to get annoying.
Edit: Appears that I have solved it somewhat. After leaving the machine unplugged for several minutes, I booted back up. Issue was still happening. So I shut it down and turned it back on. Again tried to power off with the controller, and it went silent. I thought I'd see what would happen if I tried to run a game (Rayman was in the system already). By accident I hit the Forecast channel instead. It told me it couldn't find the latest information, so I quit the channel. The Wii then shut down and went orange. I turned it back on and tried to shut it down with the controller, and it shut down to orange without an issue.
I think all this means is that I'm not going to touch the browser again for a long time. I'll see if I can isolate the issue better in the future.
