When the left/right arrow keys are used in ft_databrowser to browse trials for artifacts and are pressed quickly (usually before the trial data is plotted, but not always), the wrong trial can get displayed. Try this: 1.) Start at trial 1 2.) Press the right arrow key quickly 5 times. 3.) Wait for data to load. Trial 6 will be displayed. 4.) Press the right arrow key one more time. 5.) Trial 7 will not be displayed. Actual trial displayed depends on how queued events were handled. Mine went to Trial 3. Not confirmed on other hardware/OS. My environment info: Mac OS X 10.8.5 Matlab R2013b

Thanks for reporting! Fixed in bug 3123, current bug marked as duplicate. (technically it's the other way around ;), but I hadn't spotted this bug yet.) *** This bug has been marked as a duplicate of bug 3123 ***
