Help, big grey border when I crop now

[redhedream]

I have been using PI x3 for a long time, before that all the way back about 10 years for other PI, all of a sudden I am getting a big grey border when I crop and every time I have to go to the View, Fit In Window. I never had to do this before and it is taking too much time to edit.
Please help me to learn how to go back to the way it was. I can't find help anywhere that talks about it. If I crop the picture gets tiny and the big grey border comes up.
Thanks, I hope someone reads this and lets me know asap.

It sounds to me that you have the image open full rather than tabbed.
On the blue menu bar to the right are three icons. Click the centre one to reduce the image to tabbed. Then click Fit to Window and the image will fit okay.
