Cross-posted: I think this was my issue. Mine would work great for a few days then freeze. Tried everything and sent the unit back and got a new one. Next one, SAME exact issue. Had a friend take it to work on it who has had Formulers forever and when he plugged it in it worked fine. Then, that same unit at my house within a week, froze again, and that was today. Unplugged for 30 minutes, cleared cache etc...nothing. Then I stumbled on this post/comment with the USB and air mouse and remembered that when I gave it to my friend he had the power supply, box and original remote. Nothing else. I pulled the USB for the air mouse/keyboard remote, plugged it in and it works fine, for now so stay tuned.
I have a different air mouse remote I can try. I think I can set a button ON the Formuler remote to be a mouse if I remember correctly. Right?
This came with the unit. Here's the pic from amazon. Hope it helps someone else because MOL3 and F11Pro rock!!
