Has anyone else been experiencing lag issue with QS when a disk is inserted in the CD drive? After houling this brand new, and heavy, paperweight around the city for tech service (3+ weeks) I sent it back to Apple for an exchange. The techs could never figure out the real issue with the first computer, but that doesn't matter because the newly delivered replacment HAS the same exact problem. Apple tech claimed only one known case, I find that hard to beleive, unless I have very bad luck. Power is run through an APC, and the second G4 was out of the box, turned on, cd inserted and laaaaaaged.

Test by opening Simple Text and typing quickly, letters appearnce is four seconds after keystroke. Lag remains even after disk has been ejected.
