I have had this problem on and off for the last year or so.
From memory, this problem does not restrict itself to controls contained within pageframes, however the application I am currently working on widely uses pageframes so it is hard to say.
The problem I have is that occasionnaly, then a form regains focus, half or more of the controls will dissappear. If you move the mouse over them then they reappear.
I have tried lockscreen, refresh, setfocus (both on the parent formm, the parent pageframe and the page containing the objects) and none of these seem to work. The controls seem to come back of their own accord if you continue to use the application for a couple of minutes. Sometimes they don't come back at all and you have to quit and reload the application.
I can still reference the hidden objects from the code window and have confirmed that they are still in their original position by looking at Top and Left.
Anyone have any ideas at all???
