Hiccup in Picasa to Ipernity Button Uploader

For the past few days ever since reinstalling Picasa, and then installing the Picasa to Ipernity uploader button from the Ipernity site, when clicking on the button, having selected an image to upload, a screen appears telling me to sign in to Ipernity (I am alrady signed in). I complete the screen.
The screen on the right then pops up "Looks like cookies are blocked. Please check your browser or firewall settings".
Nothing blocked!
Is anyone else having this issue?
Separately another screen appears, which is totally non-responsive. Closing it asks you if you want to cancel upload. The other alternative leaves you with unresponsive screen???

Any ideas out there what is going on. Does anyone else have these problems?
