Make window top most when in fullscreen


Hi everyone,

I am trying to figure out how to make an app top most on Windows, once another window comes to the front. My problem is a follow;

When my app opens, it becomes full-screen, which makes it also the top most window. However, at a certain point, the app is going to have another (external) app on the front of it, and after a few seconds, it must become again the top most window in full-screen mode. But this is not working currently, the other app is still being shown in the front.

Has anyone had a similar issue, and if yes, was he/she able to solve it.

Thanks in advanced for any help.
