I have about nine multi select list boxes on my worksheet through which user can select multi items and then the selection is tansferred into a another sheet. Everything was working okay but suddenly for the past week by list boxes do not activate or get enabled when I open the workbook. Rather I have to click on the control toolbox edit button and then click on the respective list boxes to get them to work.

I do not have any code running on the listboxes but rather I have a code on a commandbutton which has no bearing on the workbook opening event. Please let me know what your thoughts are regarding this. In the properties I have the Locked set to false and enabled to true.
