[OS X TeX] my Flashmode is not running

[seroul at math.u-strasbg.fr]

I tried to use Flashmode into TeXShop 2.18
on my  Powerbook Intel Core 2 Duo, System 10.5.5.

But it does not work at all.

Activity Monitor shows that
Flasmode does not react and
Flasmode-alt reacts.

But the pdf window never changes.

Any suggestions ?

Thank you.
