Resetting Vi screen message-screen flicks.. when i change screens under Linux

[Sak1s]

i am developing an application with several screens .but when the executable runs and change vi's,the screen is flickering a bit and a annoying message appears for milliseconds .

I have attached two projects.
The Untitled_resseting_vi projects appears the message RESETING VI and also there is a white space screen when a screen is closed and the next screen is opened.
In the second project Untitled_screan_flickering.vi we solved the RESETING VI message problem handling the conditional terminal of the while loops. But the white screen between the screens exists.
Can you help me to make the screens open smoothly without the annoying white space between them?

Sak1s,

I looked at both of the projects you attached.   When I ran the VI's I didn't notice a white space after I clicked the OK button.  When the OK button is pushed, the other VI in the project is opened and started and the original is closed.  I think this is your desired behavior.  Could you describe what you are seeing more.  Also, is the white space you noticed the block diagram?
