(My next post, straight on from the last...) Is there any reason (that I've missed) that is causing really annoying lag in Logic Pro 9? Are there any settings that I should check off? When I'm flying about the screen at speed - there is a progressively worsening lag on all click operations. For example, when punching up the toolbox (a right-click operation for me) it takes an infuriating half second for the mouse to react to the changes. If I select a eraser - it's always a split second behind and selects something else above the eraser as it hasn't caught up with my key strokes. The problem gets worse as the arrange window fills with audio gubbins and plugs. The really annoying thing is that my computer is relatively new and powerful. Macbook Pro, not solid drive, Dual Intel 2.3 i7s, 8gig RAM etc. running through Focusrite Pro24 - and I'm not exactly running 180 tracks of audio - maybe 25 at most and 15 synths/samplers. I'm running Log Pro 9.1.8 32bit. The other really annoying thing is that one of my old studio lappys was a little Macbook powered by steam, with only 3gig RAM, dual 1.87s first generation Intels - and it never did this. Granted I can run hundreds more soft synths and Space Designers etc on the new machine with barely a peep out of the CPU load meter - but it lags on the most basic of things - the mouse operations. It really slows my workflow. I've also noticed that the old 'spinning beach ball of death' is quite prevalent when opening the most basic of finder windows: Applications etc - it takes a several seconds to realise what I want to do and spins the little freakin' ball. SO annoying. The old machine never did this - and it was full of all kinds of junk - the new machine is music-only and has had its permissions validated many times. Is there some magic check box that I'm not aware of? Some OS/Logic update? An incompatibly issue with the sound card? Thanks.
