Jelly bean screws up Droid 4 keyboard layout

The Droid 4 physical keyboard has had driver/software issues forever, but this update takes the cake. Pressing shift-period and shift-comma no longer produce colon and semicolon as advertised, but instead greater-than and less-than. Is there any way to fix this? Also, in Dolphin browser the keyboard is even more broken—the symbol key acts as a second space bar and holding a key makes it repeat instead of offering alternatives. Help! edit: following directions elsewhere I did a factory reset. The keyboard now seems to work okay everywhere except Dolphin, where the shift key doesn't latch, the capslock key doesn't work, and the symbol key is still a spacebar. Edit 2: The latest Dolphin beta has the same problem. Edit 3: Actually, Dolphin, Chrome, and the plain browser all have this problem. Firefox does not. DroidEdit does not, Gmail does not.
