Windows 7 - Question about "Paint"

Yeah - I know that the built in Windows "Paint" program isn't the best, but it works (most of the time) for what I need to do, and I'm not looking for a replacement.... I should probably know this, but how the heck do you 'undo' something??? In the WinXP version of "Paint", you'd click 'Edit' or 'File' and click 'Undo'. In the Win7 version of "Paint", I can't seem to find the 'Undo' feature..... where is it??!?!?!?!!!!??!!?!??!!!????!!!!?!?!?
:banghead

Thanks

 

3rd icon from the left on the top bar, or Ctrl+Z

 

Thanks satrow!!! It was driving me nuts!! For others with this "problem": it's the curvy arrow that points to the left up in the title bar, next to where it says "Untitled - Paint". Or use Ctrl+Z. Thanks again!!!

(screen shot attached just to clarify)

 

No problemo ^^, there's also an option to drop that bar to immediately above the workspace too (if you can find it ).
