We have noticed that some areas of Photojunction are experiencing speed issues with the new Mountain Lion (Mac OSX 10.8) upgrade. We have located a design issue where opening images in the layout tab is slow to load. We are currently working to adjust the program with new installers to fix this problem. If you come across any further problems of this nature please email us at info@queensberry.com and let us know. We will let you know when this issue is resolved. Edit: This issue has now been resolved. Thank you for your patience. Cheers, Amanda
