Blue Eye Macro

I have created a macro that scans a window looking for specific colors and then acts accordingly. This macro has been working fine and then suddenly it stopped working. When I looked into the issue I discovered that the colors could not be found on the screen. Digging deeper I discovered that the screen dump is bringing back a solid black image. This occurs when using the Investigator tool as well.

I have tried using the Investigator tool against multiple different windows with different programs and got the same results

Any ideas on how to get this working again?

Here is the macro code that checks for the color:

Color.Limit area of interest to coordinates("600", "250", "1150", "550")
// limit window size
Color.Flush screen dump cache()
Color.Freeze screen dump cache()
// Mouse.Click at color (RGB)("255", "65", "132", "10", "Left")
Mouse.Click at color closest to coordinate (RGB)("255", "65", "132", "10", "1300", "590", "Left")

resolution change? or something like that?
maybe u should go with the log

maybe you use bot 24 hour nonstop
