If you are running Profiler on a machine whose Windows settings has comma instead of period as the decimal separator, you cannot select "66.67%" from the Zoom dropdown list, because it should be "66,67%". If you try to select it from the list, it goes to 100% instead.

Using the + or - buttons work ok though (and it causes the value to show correctly as "66,67%")

Not exactly a showstopper...
