Hi, Gavin
How multiple screens behave depends on the version of Windows and the hardware setup. There are Windows APIs (uses TMonitor etc) for multiple monitors but these only work if you have multiple video adapters. The Dual Out cards, like Radeon, handle multiple monitors as a single desktop in Windows 2000 but actually recognize the two screen in XP. If you maximize a window with Radeon in W2000, it takes over the the total area available. If you do the same in XP, it maximizes to a single monitor. You can drag a restore window to total area so a restored window can be bigger than a maximized one! I prefer XP as a default central window does not overlap both screens. Within Delphi, the addressing is a single desktop. Watch if you create an application on a dual screen and use the right screen for the opening Window. If does not show on a standard system. I have been caught many times as I code on the left and view on the right. You can increase the desktop space of a standard system to way beyond the size of the monitor. You can then scroll around but it is a pain. One solution is to ask the user to position windows where he wants them, record the positions as a rectangles which you can then use next time. Bobby Clarke PS Thanks to everyone who helped months ago with my problem about passing function names as parameters. The problem is now solved but I have had some hardware problems which is why I just changed hardware and windows.
