OK - probably wont help - most of my suggestions are useless
But, just in case........
My motto - try the simplest solution first - even if theres a good chance it wont work - simple is good...and, anyway, it does no harm......
The easiest first way to try to solve unexplained or unusual problems with the iPad are:-
Force the offending app to close. If you have iOS 4.2 double-press the Home button to bring up the multi-task bar at the bottom of the screen. Press *and hold* any icon until they start to jiggle. Then tap the top left-hand corner of the app that you want to close. It will disappear from the list. Dont panic - youve not deleted it, just closed it. Now tap the Home screen and the multi-task bar will disappear. Re-open the iPads app and see if the problem has resolved itself. If not, its on to possible solution number two!!
Restart the iPad. Press *and hold* the Power button. After a couple of seconds a slider control will appear asking you to confirm that you really want to switch the iPad off (this is all youll be doing). Slide the control to accept. A rotating white bezel will appear in the iPad screen as the iPad powers down (it takes a few seconds, just like it would if you were shutting down your PC). When the screen of the iPad has gone completely blank, press *and hold* the Power button for a couple of seconds until the white Apple logo appears and the iPad starts to power up. This takes several seconds, so be patient. During the power up the automatic screen orientation function is disabled, so dont panic. A few seconds before the power up is complete, the iPad plays a little jingle and then youre back to the Home screen. Restart the iPads app and see if the problem persists. Apple (and Forum members) recommend that you power down your iPad at least once a week, just as you might regularly completely switch off your PC. The normal procedure of just briefly pressing the Power button of the iPad merely puts it to sleep. Most Forum members have found that one of the two methods Ive mentioned here cure a whole bunch of unexplained problems and are an easy first step to resolving most anything that happens on the iPad.
If these havent helped, get back to us and well try the more interesting potential solutions next!
