Did somebody notice differences between VB.net debugging and Providing (Bereitstellen)?

Hello,

Did somebody notice differences between VB.net debugging and Providing (Bereitstellen)?
I have a problem with my Software which uses the SPIlib.
If i start it with debugging, it works flawless.
If i start it from within the Device it works flawless (if i had debugged before)
If i start it from within the Device after a Power On Reset, it freezes (The hourglass stops working and no Input possible).

Does somebody have a hint for me?

Best regards, Stefan

Are you using a debug build of your application in both cases?
