Help! ELO touchscreen, how do I rotate the image?

[quarterback]

I swear I knew how to do this, and now I can't.   

When I first bought my ELO 15" touch screen, it appeared as if it had originally been installed upside down because things were 180-degrees off.   I remember being nervous but then figuring out how to get it rotated so it would be correct.  Well, I'm re-configuring my juke and I now NEED to mount the touch-screen upside down.... but I can't figure out how to rotate the image.

I thought there was something in the ELO software settings, but I can't find it.  I also tried my display properties but I'm out of luck there as well.  I have it all attached to the frame and base but now my screen is freaking upside down.   AAAHHHGHGGHGHGH!!!!

I hope somebody can help me out.  I guess I can try some other kind of software solution that rotates the image, but I SWEAR that there is a built-in solution because I thought I had to change this originally. 

Thanks!

Screen rotation is probably in your video driver software.

Yeah, unfortunately this older Dell laptop doesn't offer any screen rotation.    The thing that bugs me is that I swear there was an ELO touchscreen specific issue and fix.   However, it's possible that my memory of it is slightly off.  I found another post or two about this and it sounds like maybe the problem was the cursor position and not the full screen.   

I was remembering that the full touch-screen image was 'rotated' 180 degrees when I got mine off ebay, but from reading older posts here, it sounds like maybe it was just the alignment of the cursor placement.  So when you'd touch the right side, the cursor would jump to the left side of the screen.  That's not exactly what I remember but maybe that was the case.

I have some kind of rotating software around here somewhere (I installed it on a MAME cocktail table project years ago) so I'm going to dig that up.

Thanks BobA

Found a free util to rotate your screen.   Made to make an EEPC a text reader but might work for other uses as well.  Tried on my main PC and it rotated OK.
