eraser in photoshop NOT working NOR responding
I just simpily :
1. open a photo at PHOTOSHOP as background; then make a background copy for editing.
2. work on the background copy with "eraser", no response at all.
3. try erasing on the background itself, eraser hide wanted area in white, and just stop there, not erasing anything
Recently use a lot of "quck selection" and may have made some mistakes causing the present troubles.
Any advanced user here if can help out, I apprecite it greatly.
Thank you.
