GARY W.   Cosmopod completely innocent! Sorry, Cosmopod. The problem was the search add-on "Glims", which needs to be updated to address conflict issues with latest Safari updates.

Uninstalled Glims and put back Cosmo. All working fine now.

GARY W.   My apologies. After further consideration, it appears the problem with the new window not coming up is still cropping up even after deinstalling Cosmopod. It seems like you can get a new window perhaps 2 or 3 times, but then nothing. With Cosmopod, it would only come up once and then no more.

I therefore cannot say that Cosmopod is necessarily my problem, although it seems like it somehow affects the severity of it. I suspect the root of the problem is elsewhere, like with me perhaps. :-)

GARY W.   I'm experiencing a problem with Cosmopod and 10.5.8. Certainly not a big deal in the whole scheme of things, but annoying in that it conflicts with years of learned behavior.

The problem is that with Cosmopod installed, (paid and registered) when you hit the Safari icon in the dock or elsewhere, (with Safari already running but windows closed) a new window does not pop up, contrary to normal behavior. Uninstalling Cosmopod fixes the problem.

Unless I'm missing some setting or something, I assume this is a bug easily fixed, and that the next revision will address it. Otherwise, I love the application, as it makes it pathetically easy to download and convert video.
