I have placed a ps file in ID 2 (Win) and want to use the option "edit
original graphic" in the "links window" (in German: "Verknüpfungen ->
Original bearbeiten").
But I have associated my PS files not with Photoshop, but with a
graphic viewer. So the PS file placed in ID will be open with this
graphic viewer and not with Photoshhop -> I can't edit the file.

So, is there a possibility to open the psd file with Photoshop itself?
