Slider arrow button remains pressed

I have a Slider and its callback calls a function which needs some time (less than a second) to execute and which aim is to do some calulations and imshow on gca. BusyAction set to Cancel and Interruptible to off. When I move the slider everything is Ok. When I try to click one of its arrows then the arrow remains pressed and the slider keeps moving until it reaches one end. Till now I have tried within the callback; pause, drawnow, uiwait, enble/disable the slider and many more but nothing...when I remove the call to the other function everything is normal. Any idea....?

Same problem here with R2015b. I've seen that if you remove the callback and then you re-assign the callback everything works. Any other idea?

A pause(0.1) seems to solve the issue (as suggested for similar issues in other posts and reported in undocumentedmatlab website).
