Chaim,

Just shotgunning some ideas out...

Is the listbox added to the page at runtime? There were some problems with runtime objects not responding to mouse events properly the first time through for objects added to a page dynamically.

Does your pgf class have a UIEnable based Refresh() method call? Any code in page or pageframe methods?

> This got me to thinking. To make a long story short, I found out that the listbox works fine unless it's on a page of a pageframe. In fact, if I put the listbox on a form that has a pageframe, but I put it on the form, not on the pageframe, it works fine. So there's something in my pageframe mechanism that's gumming up the works.
> I experimented and found some additional info: the pageframe opens on page 2. The listbox is on page 1. If I go from page 2 to page 3 to page1, the listbox works fine. Buf if I go from page 2 directly to page1, the listbox does not work!! I am trying to figure out what happens when I go from page2 -> page3 -> page1 that somehow enables the listbox.

Then I used SYS(3270) (as per your FoxTalk article) and compared the values of the two listboxes. They were identical except stuff that just confirmed what I was seeing.
