Debugging problem

I'm trying to step through one of our macros written forever ago. Everytime a Range is used in the code the debugging process skips to this function "instring." Then the Step Into just starts an infinite loop inside the function. It is getting really annoying.

How can I stop this?

If I run the code normally it works fine.

It would be much easier to assist you if we could see the code you are working with. Consider pasting a copy of your code here (using the code tags), or post a .zip copy of the workbook.

OK I figured it out. They wrote a custom function to use in the cell formulas to return a boolean if a certain text is instring.

Everytime a cell in the range uses the function I get stuck in the loop instead of it moving to the next line in the sub.
