Change Icon of RUNNING program

I would like to change the icon of the RUNNING Directory Opus program that displays in the taskbar.

The small blue icon which typically shows up in the taskbar is difficult to quickly distinguish from other running programs which also use small blue icons.

I would be happy with a simple yellow square or something like that.

Is there a method to change the icon of the RUNNING program?

Thank you,
Chuck

You can change the color under Preferences / Display / Colors and Fonts / File display icon.

Alternatively, if taskbar grouping is on and you pin the program to the taskbar then you should get the yellow icon for it.

Leo, that's very helpful. The icon now stands out nicely when I'm under pressure and furiously switching back and forth between applications. Thank you. Chuck
