Hello. I need some help with customizing my taskbar. My desktop has a black/white theme and I want to change the icons of running programs on the taskbar to match my theme. However, it only seems to work for some programs. I want to change my Google Chrome from the default rainbow to a white version. I have done it once and the taskbar chrome was white, but after about a week, it reverted back to the rainbow wheel. How do I change it back to my other icon? Thank you.
