I am in the process of converting a program I've written in earlier versions of VFP (most recent 8.0 SP1) to 9.0 (SP1), but I'm having something really wierd happening.

I have a visual class, with a pageframe, and on several pages I have Listboxes. The problem is this: With all listboxes except one I can't click on it. I can move from row to row with the arrow buttons, and once I select the 4th page and then click back to any of the other pages I can click on the listboxes.

And get this, I have no code in the activate/deactivate event of that 4th page.

Does anyone have any idea what is going on here? BTW, in 8.0 I have no problems. Its the exact same class (in a library with other classes).
