Hi Matt,
Remove the class from that form, close the form and compile it. Now add the class.
The "Cannot Modify..." error is coming up because the class is still in memory. Issue CLEAR ALL to get rid of it.
>I have a combo box class that is acting up. When I first go into VFP I can double-click the class in the project manager and see my code in the Init() and Click() methods. However, if I run or edit one certain form that uses this class, then next time I modify the class, I cannot see the code I put in.
