I've noticed that Lightroom 5.7.1 hangs when attempting to edit in Photoshop Elements 13.1. It will sit there saying processing and make no progress no matter how much time its given. I've noticed that I can get it to work if I change the file format from TIFF to JPEG. Is this a known issue with a fix/work around?
The next thing that I've come across, is that when editing in Photoshop Elements 13.1 through Lightroom, the changes made are not saved to the file (yes I'm clicking save). To get the changes made in Elements to save, I have to go back to Lightroom open the copy that was made for the export into Elements and select "Edit in Elements". If I make all the edits again and save, it will then update the file in Lightroom. It doesn't appear initially that Lightroom lets Elements change the file.
