I don't know how I would change the looks of the taskbar entry. Another way you might solve this problem is with the "quick launch" area of the task bar. You could put a short cut to a small exe that first looks for the "interactive" version of FoxPro on the task bar. If it finds it, it could restore it and give it focus, if not, it could open a new instance of FoxPro for interactive use. So, if you were in your program and needed to jump out into the interactive FoxPro, you would always go to the same icon in your Quick Launch tray. This might even be better than having to go to the actual task bar anyway.

I have mocked this up and it is working great. Let me know if you'd like me to e-mail it to you.
