Hi,

In my application I have a TabPanel, the first tab in this panel has a button which launches a new tab for which the content is loaded using auto load. This new tab/page contains a PDF viewer control(http://www.winnovative-software.com/pdf-viewers.aspx) which is essentially an object/embed tag (the normal Adobe in browser PDF object).


If I click with the mouse into the PDF viewer to give it focus (say to scroll through the document) and then switch to the first tab and then back to the tab containing the PDF viewer, the PDF viewer vanishes from view leaving just an empty white tab.


I have tried playing with the hideMode tag of the tabs but this hasn't made any difference.


Just wondering if you might know any work arounds for this problem? I should also state that this only seems to occur in IE - I have tested with FF and Chrome and they both seem fine.


Thanks
