my brother screwed up my photoshop and i dont know how to get it back to normal. can anyone help me thanks. Tried delete pixel aspect ratio and nothing worked.

go to
View>Show>Grid

that worked thanks bio

another thing whenever i try to do a gradient from color to transparent it just does a full color...

May be a stupid question but are you holding down your mouse then dragging along then letting go ? Rather than juts clicking.

hahha yeeeeah harriw i am and it still goes full color

hmm cant see why its doing that, try changing the options for it, or just reinstall the whole thing
