I can confirm this problem with DateTimePicker ActiveX control.

I am loading this control dynamically at run time on the second page using ADDOBJECT command. As soon as it is loaded it shows through the first page and I can set focus to it.

If I click on second page (where it is) and then back on first page, then everything is OK until this ActiveX control is refreshed with new data. Then it becomes visible on first page again.

I think this came with Visual Studio Service Pack 4. Very very weird.

>What I get is :
>Initially datetimepicker control is visually doubled, one overlapping the other. You can tab to only one of them (with correct left,top) but you can setfocus to 'both' of them with mouse.
>If you cycle through the pages, after getting to 3rd page everything is normal.
>What gives ? Any suggestions other than creating 2 different classes for different formats ? TIA
