I have mainly two bugs:
the first one is already knowed: the problem is that whan shutting down windows, lcd info isn't closed.
I don't think that the IO driver may be in cause because lcd info work fine after you ask the shut down: I mean screens don't stop to change on my lcd (if I remenber well).
The second bug I have is the when I do a standby come back : lcd info become crazy with infinite pop up saying the same error. This came from the IO drv: it maybe it is not restarten.
attention, i am actually in vacancy, far from my own computer and far from my lcd
. What I just said may not be the truth 
I can confuse between lcd_info & smartie & jalcd but I'm quite shure of what I just said
