Can anyone tell me where to look for a problem when a vision client screen gets locked up? We have Panel PCs with Ignition Edge Panel. When a user touches a button that writes to tags (using bi-directional custom properties, not the writeBlocking script) the screen locks up and they cannot touch anything else on the screen. I say touch because I was remoted in via VNC and could click around when the local user could not. Anyone have any ideas on what could be locking up the screen? ---

What version of Ignition is this? The best way to troubleshoot this is to get a thread dump from the Vision Client application. Newer versions do this automatically when something blocks the UI thread long enough. ---

Ooh, yeah, I didn't catch that. Sounds like the touch screen / drivers are not responding. ---

It's Ignition 8.1.23, what's odd about all this is it happens on every single Panel PC I have, no matter the vendor/manufacturer. That's why it makes me think is something I'm doing in the vision screens/edge gateway. ---

Does it do the same in both Windows and Linux? ---

Not sure, I do have some with Linux and some with Windows. In the beginning, I had just Linux and was using Perspective with Workstation and I never heard of this problem but as soon as I started using Vision, this problem happened. I will have a job coming up that has 4 Edge devices with a mixture of both Windows and Linux. I will check that out if it acts the same on Windows and Linux, yesterday's issue was on Windows.
