I have an ACCDE file on a client computer. When you click EXIT on the program, it should run a few delete queries and QUIT. This program has run perfectly since February 2026. For the last 2xWeeks the program will NOT close (on client machine). It works great on my computer. Walk thru testing on my computer shows no error. I rebuilt the ACCDE. I did an ONLINE repair. I Compiled. I Compact and Repair done 3 times.  My error handling on CLIENT says:

"[frm_frmMainMenu.butMainMenuExit]: Error Number  3709:The search key was not found in any record. -- 6/5/2026 10:53:22 PM"

Like I said, I took the "broken" ACCDE from the CLIENT, opened it on my computer and it works fine.

I tried all of Richard's repair tricks. I am bald and still pulling out my hair.

Can anyone suggest something else I can Check??
