Thank you very much for this update Trotier this explanation was what I was asking the support of citrix people but they could not understand why it was happening I am experiencing a problem like this. I have an C# application on inventory and I have publised it to the client. Now when the client is working on an Master file updation say Item Master we have a model window launch to select Catagory of the items once the catagory is selected by "Enter Key" instead of a mouse double click the focus completely goes off from the application and whichever is the application minimised in the seamless window will pop up on the screen and the application goes to the background and then we have to click with the mouse in that screen or press alt+tab to get the focus back. To Solve this issue they suggested to give a Full Screen Mode rather than Seamless Window . The problem I found with this is in some clients machines it is still showing as a seamless window why is this happening and in some clients it is Full screen Mode. Thanks a lot for the article and I am planning to set the value of the registry to no. 14 DON'T SEND DISABLE (Value: 0x8000) I think it will solve this problem if there is anything more please send it accross.

This happens either when an app generated error, like not completeing a required field, appears, or when a user tries to do something impossible like trying to go to the end of a list when you are already there. the app does not close - just minimizes.
