Image Size in Photoshop automatically reverts to tiny resolution
I'm having problems with Photoshop, and it's been going on for about 3 weeks now.
Every time I work in photoshop the resolution reverts to 1 or 2 pixels - even if I have set up new doc at 72 - later on down the track it always reverts to this tiny size.
Snapshop image below show the resolution.
BTW - I haven't done anything different than before.
Can someone please explain....how to fix this and how to avoid in the future?
Thank you!
