Photoshop 7.0 - toolbars



I sure hope you can help me....on my tool bar my paint bucket has disappeared, along with the ruler, airbrush and pencil. Yet, I have a healing brush and path selection tool. Why all of a sudden is my tool bar different than what I had two days ago at work? I removed the program completely and reloaded it....the tool bar remained the same. I've always used the paint bucket at work, but then it vanished. I also have this program on my computer at home....I checked the tool bar (I've never used it at home) and it's the same as the one I have at work now. In other words, my toolbars all of a sudden don't match the one that shows on all the sites, but the one at work I know did. Please help me.
