Dolphin Bar not working in steam

[ClemmerC]

Not sure when exactly this happened. I launch my Dolphin Emulator Wii games through steam. This has worked exceptionally well the last year or so. However, now Steam suddenly doesn't know what to do with the dolphin bar, when I launch a Wii game in steam, the wiimotes will not work. If I launch a Wii game directly, not through steam, the wiimotes work as usual. What has caused this to quit working?
