Railworks America

Usually, I run Railworks full screen. For testing with the ControlStateDialog window open, it has to be run in windowed mode.
I noticed there is no taskbar icon, only a small generic exe icon.

How can I add a proper taskbar icon? I used ResHacker to give Railworks.exe an icon, but that doesn't show on the taskbar?

I recently noticed the same. No big deal for me, however, a generic EXE icon is the least of my worries.
