Font Issue in Vision Client

Hi all,
I’m experiencing the following issue: pages show different fonts depending on the way I launch the application. If I launch the application from the designer with the Tools-Launch project-Full screen command all fonts are showing correctly (all fonts are logical fonts of type Dialog) - next some examples

On the contrary if I launch the application by means of the Clientlauncher fonts appear differently (biggest problem is that labels are no more sized correctly!!!) - next the examples

If you pay attention, also the system java icon in the last dialog titlebar looks different.
Any idea?

Processor: Intel Celeron N3160

Thanks in advance, regards
