I'm new to Logic X. All of the downloadable loops and samples from Apple have been downloaded. Currently if you press the Show Loops icon on the menu bar the loops show for less than a second and then dissapear. If you use the menu View>Show Apple Loops then the Loops appear as expected. Several menu items are working like this- when using the menu icons the item will only briefly show but going through the menu works. What's going on, how to fix? Thanks
