Move program Icons in Taskbar

[Samkent]

This is more of a irritation than a real problem.
I have 2 different programs running. Access and IE.
I will be doing the C&P form IE to Access. Basically entering new data from a website into our database. I may do 2 or 3 customers then all of a sudden the active program icons in the task bar have reversed.

This is not the quick launch icons on the left.
This is not the clock etc icons on the right.
This is the only two programs I have running.

I prefer my active programs in a certain order. Essentially the order that I open the program first thing in the morning. It's a muscle memory thing.

I am forced to shut down one program and restart it to get it back to the right. It gets worst as the day goes on when I have 4 different (required) programs running. I may have to shut down and restart 3 programs.

Any way to just move an icon??
