Hi Denis
Nice to see you visiting and making your first posting
Messages can be a) set to a timed amount or b) set so the user has to click a button to close (usually a button with the caption= OK)
When its vital, I use b).
When its e.g. a confirmation mesage I may use a). I usually set the time to be brief otherwise it can be a nuisance if coming up frequently.
From the info you have given, I'm not sure which message you are referring to.
Keep an eye out for it occurring again and see if you can catch what it says. The screen number would also be very useful, and which button you clicked to make the changes/deletion.
I wonder if other members have any comments on this subject?
