Hi there,
I just built an application from a vi and I am encountering an error:
LabVIEW: Null window.
The top-level VI "name1.vi"
was stopped at unknown on the block diagram of "name2.vi".
The application runs smoothly until the user selects some hotkeys to open a simple subvi briefly during execution in order to check on a file path. This hot key combination works perfectly when the normal vi is running and the subvi displays the information and then closes and the vi execution continues. Why would it not work when it has been built as an application??
Thank-you for any help you can provide!
