Hi. I have a multicolumn listbox with some elements disabled. When I'm using the value change in Event case, it seems like the disabled elements are not disabled after all. If I try to select a disabled element the previous selection is no longer selecte and the program enter the value change in my Event case. When probing I can see that the vlaue changes to -1 if I select a disabled elemnt in the multicolumn box. How can I avoid this happening, nothing to happen if a disabled element is selected and the previous selected element to stay selected.
