@Deacon: I've split your new posts into a thread that I've moved into the beta discussion forum due to some of the data that's been posted.
@pimento: that's interesting if it's better later in the day. though can you have a look in the system event viewer & see if there's any winamp/wacup reported errors (I've a feeling that what Deacon has posted before I split the posts might be the same sort of cause of issue).

Sorry, I explained badly, it's more likely to not open later in the day. I just tried it now and it's failing to open, I had thought perhaps it was related to being docked but I'm on a work trip so no dock here. Anyway, the first time it started the two background tasks as usual and didn't load, I killed them and tried again, that time it didn't even load the tasks but I got two entries in the Application log (nothing in the system log) and then I tried again and it was back to the two background tasks and nothing else. I've attached the details from the two events here.
