“A running program isn’t compatible with certain visual elements of Windows. Click here for more information.”
Running certain programs will cause the informational message The Color Scheme Has Been Changed To Windows 7 Basic to be displayed. Aero themes were introduced in Windows Vista and incorporate an advanced GUI (Grapical User Interface) that makes window borders look transparent (among other things). If you see this message when you start a particular program, it means that that program is not designed to be used with the Aero effect as it doesn’t recognise the advanced GUI utilised in it when it’s active.
Note that this is not a problem with Windows 7. It is a problem with the program you just opened.
If the fact that your program changes the Windows Color scheme turns out to be a problem, you don’t have too many options. If you are using an old version of the program, a newer version might be compatible with the Aero theme: download it and try it. Is it possible to live with the Windows 7 Basic color scheme? I run an old version of Adobe Fireworks (from when it was owned vy Macromedia!), which insists on changing my color scheme to Windows 7 Basic, and I can cope with that. It also changes the way that Windows 7 behaves. For example, when hovering over multiple sessions of the same program, Windows won’t display the small thumbnail image of each session as it should. Instead, it will display a very basic “drop down” selector to choose a session, as shown by the image below:
When I open Firworks, the screen actually goes blank momentarily, and this also happens when I close Fireworks and Windows 7 returns to the aero theme.
