Well darn! I didn't find the answer to removing the title bar while I was using my Polaris, which is qvga. I still have one that's being repaired. When I get it back, I'll retouch this issue and try full screen on that device.
Oddly enough, Opera 9.5 goes to full screen perfectly on both devices, but I don't know what method it uses. Could it be something with the SIP?
On the Polaris, while I was fiddling with the home screen, I wanted to remove the bottom status bar which contained the two soft menu's, one program, dcinobar.exe, worked under most circumstances, but the SIP gave it problems, similar to the pic above. Specifically, it would seem to work, but the first time a program used a SIP and put that little icon down there, the gray bar stayed with the icon there till you soft reset the device.
When I switched over to the vjay555 program (still on the Polaris), where you can set the top and bottom bar removals independently, (and I learned to tweak it properly) it seemed to work much better than dcinobar. But since I've not yet tired of tf3d and removed it, I've not tried either on the new HD.
You may be right, but I hope not. I sure like showing off that little b4p program I wrote on that large hi res screen, and it would be so nice to be able to use all of it. I'll write more later...
