AppStore users of the 6.1.1 faced an issue with external files and Textures library drag’n drop, both issues were caused by some glitches in the new sandboxed version of the app. I’m working on the update and 6.2 ill be send onto the AppStore this week. Hope it will get reviewed quick.
As for the closed down sharing compatibility – it will be back, but later. I’m still working on a new sharing library and we already have Facebook and Flickr support. This one looks better and is much more stable, but it will take a while to polish it + it requires Mac OS 10.7 to run. So, nearest release of the PhotoStyler will no include this library since I’m trying to keep 10.6 support as long as possible.
