Okay, there is a "Split at Y" in the generate menu. Is there an easy way to split a curve at an "X" position. I'm rusty - maybe I forgot a method that I should remember, but I'm not finding a menu entry or in the help.

I guess one way to brute force it would be to copy a curve, then paste it back into the same graph, then Truncate X for the original curve, then Truncate X for the new curve so that you have the portions split the way you want.

Yes, that's one way. Or (depending on your scaling) you can Edit>Swap X,Y, then Edit>Split at Y, then Edit>Swap X,Y again.

David,

Thanks. That works, but I have to tell you that lately every time I touch DPlot, I get a new glitch. After I copied the truncated curves back to my original plot, I next did a "Find Intersections" between that line and the longer line that I had not truncated. The command completed and added the labels without any complaint. But then I tried to move the labels around and the labels would not move. It looks like I grabbed the outline of the label, but when I let go of the mouse, the label would snap back to its original position. I tried moving 4 or 5 other labels, but I could not move any of them.

But if I stop what I was doing, save the file, then exit DPlot, then reopen the file, then everything would work again.

I seem to be able to repeat this if I take the same steps.

8gb memory on Win7-64 Enterprise. Office 2007.

Any idea what might be going on or how to trouble shoot it? Could I have a bad memory stick and have some kind of memory corruption? I haven't seen anything strange in any other application. And again, if I save frequently, quit, then restart DPlot, it seems work again.

David,

Ignore above. First step in trouble shooting is to not load some of my "TSR" utilities, esp. AltMove Manager, WizMouse, and CrossHair - anything that has to do with the mouse.

Good info. I'm not familiar with any of those but will look into them.
