I have a question about these System Objects. What if the user changes his/her properties in Display Settings while the app is running? Do these colors change?
Quote from MSDN:
ActiveBorder: Gets a SolidBrush object that is the color of the active window's border.
ActiveCaption: Gets a SolidBrush object that is the color of the background of the active window's title bar.
ActiveCaptionText: Gets a SolidBrush object that is the color of the text in the active window's title bar. "
To me this would imply that the colors are changing. But then again I have been known to be wrong at times.
Hmmm... what's a signature?
Im looking for some advice. I have written a little thread that will check to see wether a text file has been updated. It compares the time for example. I as wondering, whats the best way to have a thread execute a method every few seconds without completely bogging down my main thread?

Memory is allocated for all objects (primitives too). GC cleans it up. Note: That unlike C, everything goes onto the managed heap, so one can "dynamically" create a valuetype array. MS recommends using classes above structs for performance reasons.
Boxing is very expensive. Everytime you add a valuetype to an ArrayList for example it gets boxed (and making a typed collection doesnt get rid of it AFAIK). With a class you dont get that. Unfortunately the only place I could find something now, is in the EMCA 335 spec Partition 5

• Do favor using classes over any other type (i.e. interfaces or value types)
On the MSDN/C# homepage there is only a very informative article on performance.
