Almost every time I close out Photoshop and reopen at a later time or date, settings are being changed.  I'm not doing anything but I am constantly having to go back in and change my pallets and workspace.

Yesterday I began to edit a job I had shot earlier and my history is not working.  When I do something such as crop, it will erase the last entry and show crop only.  I cannot go back more than just the one step and only if I use "Ctrl Z".  I have searched through preferences and all of the menus and cannot figure out how to reset the history to the original setting.

Are there any photoshop experts that can help me?

Would it be easier to reset all the settings to default and start over?  Can you tell me how to do that?

Thanks.

u may have to press alt + command + Z. command + z is just going back and forth

im shooting in the dark here...try preference -->performance, look at history states. the default setting is 20.

This is very strange.... it worked.  Thanks.

I tried that yesterday and it didn't do anything but today I shut PS down and reopened and that made the difference.

Thanks a lot.  Next time I'm coming to the city, I'll buy you a brew.

Best to you!

It's also sounding as though your overall preferences might be corrupted. You might want to delete the preference file. (It's an old article, but it's still valid, even in CS2/CS3/CS4.)
