I'm having a problem with the virtual keyboard. When I'm tapping away, there will be times when characters don't register the taps, instead I get blank spaces, capital letters, hard returns, etc. I've gone into the input menu and I'm using the "small keys" option for the keyboard. The gestures option is grayed out, which means, I'm assuming, that gestures should not be picked up when tapping keys, yet I'm still having problems. I tried changing input to "large keys" and leaving the gestures option unchecked, yet the gestures are still active when using large keys as well, even though the input screen tells me they're not. Is there any way to turn off the gestures option altogether?
Any help would be appreciated.
