Well it could be that it isn't compatible with ff3. Will keep that in mind the next time I post something here.
Edit: Okay I can't see the zoom button on Safari as well. Must be after the skitch update something is going on in there that needs to be fixed. Though for now one has to drag the image from the skitch window onto a new tab
. Next time we only post direct links.
@prakash: Why? And what makes you think OS X can't do that? That too without the said tweaks. Not sure about what Vista is capable of though.
