Found an issue in Photoshop Version 13.0.1.
This is not a great issue but i think this could be easily fixed by Adobe.
If you want to link multiple layers in an image via rightclick and choose "Link layers..." it doesn't work as expected. But if you issue the link layers command in the layers palette it works. Same problem in 32bit and 64bit Version.
System: Windows 7 x64 SP1
Photoshop-Version: 13.0.1 (x32 and x64)
can anyone also confirm this issue ?
