Follow actions not working

[foop]

I have been trying out some of the ideas in this tutorial on follow actions to create drum fills:

http://www.ableton.com/index.php?main=t ... b=tips1104

He says:

First off, the Launch Quantization has been set to 1/8, allowing us to trigger the fills from within a bar, not just on the downbeat. Secondly, the Follow Action Time has been lowered to one sixteenth note. This means that the Follow Action is performed one sixteenth note after the clip is launched. In this case, the only Follow Action is "First," which re-triggers the main beat.

However, I cannot reduce the time to less than 2 16ths.

Is this a bug, or do the 'allowed' Follow Action Times depend on something I am not aware of? I have everything else set up as in the tutorial example i think....
