I have a project that runs on a nuc its setup to swap between 2 windows and it will work for a while then it freezes on 1 screen and have to restart the nuc to get it going again.
Please tag the question as Vision if you want to attract the Vision guys.
There's nothing obviously wrong with that script or setup. I've done virtually the same thing for ceiling-mounted Vision-based dashboards.
There's almost certainly something else wrong. Client freeze-ups in Vision are almost always caused by abuse of the foreground UI thread with inappropriate scripts, particularly in runScript bindings and propertyChange events. You should search this forum for related topics.

Here is a copy of the console when it freezes
Well, that's a doozy. Something in your application is leaking memory in the Vision client. You probably will need IA support to help you track that down.

You're running some Ignition 7.X version. You should make sure it's at least the latest available 7.9.X release, in case this is a known client memory leak we've already fixed.
You should also really strongly consider the upgrade to 8.1, since 7.9 is now unsupported.
This is the version we are using.
Well, then support is your next best bet. 7.9.21 is out, but doesn't have any memory leak related bugfixes. Support may be able to help you identify what's going wrong with your project.
Try giving your client more memory to play with (in the project settings) to see if it runs longer before dying. Or runs indefinitely.
Not the designer. The actual client(s). It's in the project properties once you open the particular project in the designer.
