What code do you have in the Customer Form?

I got the same result with a vanilla copy from the TechHelp download.

The ShowTip() function is trying to run while the navigation pane is still the active window instead of the main application window (I think).

I resolved it by modifying the ShowTip() function:

Private Function ShowTip()
    DoCmd.OpenForm Me.Name
    Sleep 100
    InstructionLabel.Caption = Screen.ActiveControl.Tag
End Function

Whether that is the best solution I don't know, but it seems to work and I'm not finding any issues opening from any forms.

Kevin, I didn't change anything in the database download.

Donald thanks!

Happy to help... Butttt...

As I clicked "Submit" on that, lol, I could hear Richard's voice, "In a finished database, you're going to lock it down so the navigation pane isn't available to the end user, right?"

On Error Resume Next also works.

Thanks Kevin. I'll try both suggestions. It just seams really weird that it works from the menu, but not from the Nav Pane

@Kevin Robertson,

I just thought of that too and tried it... Sometimes I get so used to having to find round-about ways to solve things, I overlook the simplest solutions, lol
