If I have a listbox of items, and everytime the user click on an item on the listbox, the corresponding cluster appear. If the user click on item A, cluster A appears, click on B, cluster B appears, etc. With every cluster, if the user click on the OK button, a checkmark is sent back to the item in the list. However, the user has to be able to scroll through the checkbox even if OK was not clicked. How would you do something like this? I tried to put the event structure for OK in, but the program will not let me scroll through the list of items in the listbox until OK is pushed. I need for OK to be just an option while I scroll through the list. Thanks
