Help PS7 has quit working?

This may sound like a stupid question but I have been doing a bunch of work on different photos over the last few days and every thing has been working fine.

Today I had the program open and was working on a project with the eraser tool and I had to leave to answer the phone. When I left the tool was working fine while I was away from the computer it kicked into sleep mode. When I came back and went to start where I left off the eraser tool would do nothing.

I have since garbaged that whole project, restarted my computer reset all the tools you name it and I can not get that or the paint brush to work.

The eraser tool will make a very fine scratch no matter how I set it.
What happened while I was away from my desk????
I do not have any kids or anyone else that would have messed something up.


Does anyone have any ideas, is it something simple or should I try reloading the program?

had something similar to this happen. it was solved by resetting the preferences by holding Ctrl+Shift+Alt right after launching Photoshop.
