c# form losing focus

When i run my application with visual studio IDE, the application runs fine. When i run directly the executable it is not running fine.

My app creates two forms. First form losts focus when the second form is about to create. The first form UI frezzes when i run directly executable.

Please give any suggestions how to debug the problem.

Setting the First form property Topmost to true solved the prolem.
