weakness of TrackIR 4:PRO

[PNP]

I just received my TrackIR 4:PRO yesterday and enjoyed using it in Flight simulator x . This early afternoon I went to use the TrackIR 4:PRO and found out I am unable too because of too much sun light. My Sun room was turned into the computer room and now it looks like I need to add blinds to block out the sun If I plan to play during daylight The sun gives off too many IR sources of light causing the TrackIR 4:PRO not to work. Considering I have 18 large windows to provide Blinds for looks like I am playing with TrackIR 4:PRO in the late evenings to early night when the sun starts to set.
