10.5 SDK Makes my Progress Indicator Choppy

Hi,

I’m writing an application that requires Mac OS X 10.5 or later so I thought “why not set the active SDK to 10.5 instead of 10.4 ?” So I did and after much searching I found out that this caused my progress indicator to become choppy. When I change the value of it, it gently moves to the new value with a nice animation but with the 10.5 SDK it directly goes to the new value without the animation. The progress indicator is not indeterminate by the way.

Is there something wrong with my SDK ? Does changing the SDK change much ? Does somebody know a work around ?

I tested this on 10.5.8 PowerPC running Xcode 3.1.3

Thanks!
