Got an error I’ve never seen before. On launching the client, I got:

This appears after the main window appears, and with “Downloading from Database” is in the little status window.

Clicking OK clears the message, but the error pops up when opening other forms.

After closing the client and relaunching it, the error still appears.

Anything to be concerned about?

Logging out and then back in, on the workstation, fixed it.
