I’m hoping someone can help me. I’m using Ignition Designer, but it seems to be frozen. I’ve tried power cycling the computer and restarting Ignition Designer several times, but it remains stuck. There’s a window open (screenshot below) that I can move around by dragging it, but I’m unable to click on the Yes, No, or Cancel buttons. Does anyone know how I can get past this?
Non-responsive UI. That means some event script is hogging the UI thread, typically with some kind of sleep or infinite loop (including wait loops). Such are not allowed in Vision UI events. In my experience, this is always a programmer error.
Those thread dumps it reports should be examined for the culprit task. If you cannot understand the contents, post one here (with code styling), or open an IA support ticket for them to look at.
You can't. You have to kill it from the OS. Then, don't open the problem window. Extract its XML formal (without opening--shift-right-click) and hand edit it to delete the problem script. (You may need help with that, too--the format is cryptic.) But don't try this part until you determine which script is killing your UI.
I managed to find a backup that contained nearly everything, with only a couple of hours of work missing, and I was able to successfully import it back into the designer. Thank you very much for your help. I believe this issue is now resolved. By the way, you were absolutely right—it turned out to be a problem with poorly written expression logic.
