I have a custom toolbar, multiply custom menus, as well as many custom macro buttons constructed. i have attached to the workbook as required, saved and closed workbook. Now I transfer the workbook to a memory stick and load into my laptop(same operating system and excel version), and I open the workbook. My custom toolbar and menus are present but they are not fully functional, some are defaulting back to macro generic status. i load this woorkbook into another PC I have and the result is similar but not identical. Is it a workbook error, an add-in required, workbook file type, or is it something else? I would really appreciate some insight to this one, I am at witts end......Thank you.
