I've made a form exactly as Q157048 says (in fact, just the listbox part and the 2 properties to the form) and it works just fine. So, you have to look in your code for something wrong.

Eventually, restart a test form from scratch...

Probably just a dummy idea: Probably you Cut&Paste the methods' code from the MSKB. Are you sure you didn't CTRL+V twice in the List's Click method (ie copy the same code twice in this method)? This would explain the behavior you reported.

>I have created a list box with a check box in it as described in KB article 157048. Basically, it functions like the
