Problems with my wireless keyboard
When I press the left shift key together with the t-key (to create a T) it does not work. From this time the following keys do not work or do not work as they should: Return, Enter, Arrows. If I restart the keyboard it works correctly until i press the left shift and the t key again. The fault is definitiv in the keyboard. Has anybody an idea?
