Image not updating after modifying in external program

[joudavonk2]

XnView: MP 1.8.3 - 64 bit
OS: Windows 10 64bit

When I use XnView shell action edit with with photoshop assigned (but that can be any extternal editor), make a change there, savit it, close photoshop and go back, image will never update regardless how much I try, going one image forward and back, close full screen and open it again, I have to restart whole program, which is pretty annoying, old non-mp version was not doing that.

Effect: It forces me to restart the program everytime I want to see changes made by external program

To reproduce:
1. Open XNView MP
2. Select image and use "open with" eg. photoshop
3. Make a change there and save it
4. Go back, reload image
5. Image will remain the same until restarted

Actual behaviour (bug): Image never updates in full screen, nor thumbanil

Expected behaviour: Image updates if date modified changes or add reload button
