I got the part about "it worked once". I'm asking some questions directly related to the situation in order to help ferret out what exactly is going on. Could you re-read my post and see whether you can provide any additional information based on the questions?

>>OK, so the class is indeed instantiating? I mean you start with a oEXEClass either undefined or NULL and then when you run the code the class gets created, I mean if you look at oEXEClass in the debugger it is there and has PEMs, but does not become visible even though there is a this.visible = .T. in the init? Form class I'm guessing? Long shot, but it's not somewhere like outside the viewing area of your screen, such as top 2000 or something?
