I have Elements 15 running under Windows 10. If I attempt to open a file in the Expert mode, I get a tiny fraction of the file in the upper left corner of the panel. I also have the photo in the photo bin and it exists as the background layer in the layers panel. I have never seen this before and have no idea what to do with it.
I can drag this tiny file until it fills the screen, but then I still have no idea what to do. If I cancel this photo everything goes away. When opening in the Expert mode, the "Place" open selecction is inactive.
If I open the file in the Quick mode, everything appears normal. If I then switch to Expert mode and the file is a PSD, all the layers are there and I can do all of the edit functions that I have used in the past.
I can't remember when I last used the Expert mode--may last spring.
There is a known bug in PSE15 when
- you are in Expert Mode
- you have set your preferences to "allow floating documents in expert mode"
In that case, all the files you open are only shown as a stack of small windows in the top left corner.
If you don't change that preference, use the 'layout' icon in the bottom icons strip and choose "All floating". This bug has been corrected in newer versions.
