As headline, it doesnt take much effort to bring wavelab pro 9 on mac down. On my system, all it takes is to load a new effectchain preset in the mastersection, when theres already an effect preset loaded. Wavelab crash everytime. Workaround is to manually remove the plugs in the mastersection and then load a new preset.
I am new to wavelab, so I dont know if this is an oldtimer bug, or if its only me who got this problem. I have only brainworx digital v3 and waves ultramaximixer on my chain (both legal, of course), so it shouldnt be a problem.
