Hi Yair, Thanks for the input so far! So, I just double and triple checked the three points you mentioned: 1.) The main VI's Window Behavior is set to "Default". 2.) I don't access/modify/call any properties/methods of main- or sub-VI prior the point when I call the subVi. 3.) The Source File Settings of the main VI are set such, that it exclusively uses the set VI properties and doesn't overwrite any parameters of the window appearance. In the application builder I cannot customize the VI properties of the sub VI, which I assume is normal as it is "only" a sub VI and not the main VI. Due to customer confidentiallity I'm afraid I cannot simply upload the source code, but if I shouldn't figure out a solution soon I will create an example-version of the pop-up functionality as I have implemented in this project. ---------------------- edit: On a sidenote. I can't really operate the application in the main VI. It does wait for the subVI conclusion. But running the subVI "modal" should not even allow doing anything on the main VI front panel.

Hello everyone, Welcome to my first post with which I hope to not embarrass myself I'm currently working on an application in which my main-VI produces a pop-up on startup. It is implemented such, that the main-VI simply calls a SubVI in which I use according invoke- and property-nodes to make sure that the frontpanel is shown in the correct size/postion/etc. - you konw the drill. The pop-up contains a list of checkboxes that the user has to check manually - it is a checklist in that sense. Once he completed checking the appropriate boxes the user can close the subVI frontpanel and continue with the actual application. I have set the "window behavior" (VI Properties>Window Appearance>Customize) to "modal" since I want the frontpanel to be frontmost and obligatory to complete before he can continue on the main-VI. However, here is my problem: After building the application/installer, when I run the application the pop-up does show up, but the window is not showing modal behavior, i.e. without even completing the checklist I can already use the application in the main-VI. I assume, when the application is built/run, only the VI properties of the main-VI are considered relevant for the execution and the VI-properties of the subVI are not even registered. So how can I make sure, that the subVI frontplanel behaves as intended in the final application? Cheers, and I hope I provided the necessary information to give you an idea of the issue. Vinz
