Missing user interface controls

[Miki2006]

I have unusual events with my program written in CVI. After half of year I decided to add few more controls on the user interface panel. When I finish adding few more buttons, and text boxes, I realized couple of already functional old buttons are missing when I run my program. Those buttons are there in *.uir file with call back functions and everything was functioning fine but now  buttons are missing in run?

Any idea what is happening here?

May the "Initially hidden" checkbox be marked for those controls? You can see it highlighted both in the Edit control dialog and in the Attribute Browser:

Thanks Roberto,

Yes, You are right. Is this happen due to project was re-open by newer CVI revision? I do not think that I switched off  this controls.
