Finder windows corrupted since Tahoe
I updated to Tahoe this morning and now despite two reboots and restarting finder and apps, every time I save a file or try open a file from any app the finder window extends across the whole screen and can not be resized and remains blank, the only way to get out of it is to hit Esc but I can not save or open files now????? I just tried now to attach a screenshot but the same thing happened so I had to drag the image off my desktop into this window - I am on deadline PLEASE HELP
