I consider myself a pretty advanced user of Excel, but this one has me stumped. I don't deal with toolbars very often, so I am in uncharted territory. I have a group of macros. At one time, when I ran one of the macros, I realized I had a circular argument and it created an error. No biggie. I fixed it and everything is hunky-dory. However, even though I do not have it is specified anywhere, whenever I run the macro again (without the error) the circular reference tool bar pops up in the middle of the screen. I have searched high and low in the basic set up options and I know I have no lines of code loading this toolbar. Does anyone know of any place that this tool bar is magically appearing from? It doesn't happen in any other macro or file except the one I mentioned.
