Hi,

I write codes in delphi 5.

I find that there is something quite strange. I put combo box in a
panel and then put the panel on another panel. The nested panel is then
put in a tabsheet, which is one of pages of page control. The page
control is then put in a form.

I find that when the nested extent of containers is large, the combo
box component cannot be set invisible dynamically by codes.

Why?

Could I modify something in the code so that I can do this?

Thanks!
