err:ole:ITypeInfo_fnInvoke did not find member id -514, flags 0x2!
Spammed on every cursor movement in youtube downloader, very nasty.
After a bit of testing I'm seeing this error in a lot of other applications, such as Google Talk or Worms 2 installer. I'd really recommend downgrading it to a WARN.
