I also have the problem of losing the mouse when using Launchbox 10.7 after several emulators launch such as Dolphin 5.0 (11401) and Snes9x 1.6, Higan 106, and Mesen (latest ver). I think it worked with Launchbox 10.5 or 10.6, don't remember which but it was present earlier in the year. I also find it handy to have the mouse to use Windows functions when an emulator is running.
