LabVIEW Idea Exchange
Summary: The new Manage Trusted Files window is uncancellable or takes a long time to cancel.
Details: I opened a project that had been developed in LabVIEW 2025 Q3 in LabVIEW 2026 Q3 for the first time. This is a large project, it contains several thousand VIs. I opened a simple VI that was part of the project and that depended on From JSON Text.vim (part of the excellent JSONtext VIPM package). The VI had a broken run arrow. The Error Window correctly contained a message explaining that the VI depends on code that hasn't been marked as trusted yet. I think this is all expected and correct behaviour so far.
Next I pressed a button named "Manage Trusted Files..." or similar. This popped up the Manage Trusted Files window. I let the window work for a few minutes, without any visible progress. Realising that due to the project size this operation might take a long time, I decided it's best to cancel and uncheck the "Prevent executing untrusted VIs or loading untrusted executable code files" option located in Tools>Options>Security.
I pressed the Cancel button. I waited around 2 minutes - there was no visible progress. The screenshot below shows what I was seeing after the Cancel button was pressed.
I decided to terminate LabVIEW using Task Manager. This cost me a few minutes, as I now had to re-open (re-load) the large project, which takes a few minutes.
Pressing Cancel should take effect immediately.
I've created Bug 4084947 for this issue.
