I work on two monitors mostly. I have an external monitor attached to my laptop, and usually I use this for form and report design, and the laptop screen for coding.
Sometimes, when the database is used by someone with just one monitor, pop up windows open on the monitor that is not present. To the user this looks like nothing happens when you click a command button.
With both screens present, you can drag a window between screens with the mouse.
With just one screen is there any way to move the window back onto the screen so you can see it?
PS I think it is the case that the problem only occurs if I have set the "auto center" property of the form to No.
