[TxMt] LaTeX Watch problem

[Piero D'Ancona]

After some minutes I'm using LaTeX Watch (which BTW is 
simply wonderful and makes writing in latex a
pleasure. Try it!) the Skim CPU cycles go up to 35% (also 
when both TextMate and Skim are not active or in 
the backgroutnd). 
At the same time the process "ATSServer" goes above 20%.
Pretty puzzling since this should be the ATSUI - Apple
Type Service thing, how is this related with TeX?

Am I the only one experiencing this?

Thanks
Piero
