I was trying to do something where I felt like I should temporarily check my man-card and read the directions, so I clicked on the box of interest and pressed F1, and got the above error. I tend to do a pretty minimal DMD install so thought I might not have installed help, so I did a Repair install, which indicated that help was in fact installed, but I ran it anyway. After the install, help opened once and now is back to displaying that error, whether invoked from within ladder or via the menu. Any ideas?

Bring up a System Config dialog or an instruction editor dialog, and try F1.
-
Weird. Not only did that work, but now it works from the menu and also by clicking on a box and hitting F1 without opening the editor dialog for the box, which is what I was doing before.
-
OK, it's specifically ENDC. If I click on that and hit F1, or try to open Help from the Menu while clicked on and ENDC, I get the error.
If I'm clicked on another box, say a MATH, and either hit F1 or open Help from the menu, I get help on MATH. I guess I never realized that opening Help from the Menu (which I don't do much) is context sensitive to cursor position. I assumed it would just open to the beginning of the help file.
Click on an ENDC and see if it opens.

Duplicated it. That instruction just isn't "hooked" to the specific ENDC Help Topic. Easy fix.
F1 is CONTEXT help - not just launch Help. If you are in a dialog box, F1 brings up the Help for that dialog box. If you are on an instruction, it (should) bring up the Help for THAT instruction.
-
Exactly. I knew that F1 would give help on the cursor-location instruction, I just was not aware that opening help from the DMD menu would as well.
