Id say, reflash you device with the same or the newest whichever you prefer Id say its from some other app conflicting with the sys.... just a guess but I had the same keyboard and when it was on the on screen disappeared and when it was off the on screen came back no problems, when the bt icon was displayed or not...

my igo slim was stolen and now I have a dinovo mini, but I never even had a hiccup with the igo.
