This is not a complete show-stopping bug but Logic Express (9) recently started having issues with horizontal scrollbars -- they center themselves. Occasionally they work as they are supposed to, but most of the time they immediately return to the center, which is really irritating after a while. I'll be scrolled all the way to the end of the timeline for example, and I decide I want to scroll back left slightly; I click on the scrollbar and any kind of drag makes it jump back to the center. It acts like the mouse cursor was there, too.


Reinstallation and trashing preferences did not fix the problem.

Mac mini, Mac OS X (10.7), 2.4Ghz Core2, 4GB RAM, GeForce 320M

    I'm having the same problem with Logic Pro 9. Exasperating. I didn't upgrade to version 9 until Lion forced it upon me... and am wondering if this bug is related to Lion.

    Same problem. Searched everywhere and cannot find an answer. VERY irritating - especially when trying to edit in Piano Roll. Help Apple!!!

    Just found a short-term solution until Apple (hopefully) fixes the problem. If you have a mouse with a scrollwheel, hold down your Shift key while scrolling and it will scroll horizontally. The scrollbar doesn't jump when you do this.


    BTW, in case Apple monitors these posts, I am using Logic Pro 9 on a Mac Pro with OS X Lion. The scrollbar problem did not start until I upgraded to Lion.

    Same problem here, but it seems also related to the screen in use, at least in my setup. I'm running Logic on my MacBook with a native screen resolution of 1200x800. I have a second screen attached above it with a resolution of 1920x1080 which I use for the main Arranger screen, the MacBook screen itself is mainly used for displaying the mixer and AU's.


    When the arranger screen is on my larger display the horizontal scrollbar is flying all over the place when I try to move it, but when I have the arranger window on my MacBook's screen it behaves normally. Seems like if Logic gets confused by the different widths of the screens, like if it is behaving to have 1200 pixels to scroll on while there are 1920.


    Whatever happens, it's kind of annoying...

    Same problem for me.. Mini OS X 10.7.3 with standard keyboard and mouse. No solutions that I can see?

    Having this same problem! Vertical scroll works perfectly. Horizontal centers back whenever it wants too. Very Annoying! Almost impossible to arrange regions precisely either in the main arrange or piano roll. Avid Logic user for the past 3 years and never had this problem...until I cleared and refresh my Imac 10.6.8 and reinstalled Logic Pro 9 w/ lasest updates.


    Help! Anyone!
