Hi @keith-bcr,
This is a known limitation in Glass Alpha. Remote connection types like Dev Containers and WSL aren’t fully supported in Glass yet. The prompt you’re seeing loops because the extension can’t actually activate in the Glass environment, even after installation.
For now, you can work around this by opening Cursor in classic mode:
cursor --classic
You can also use the “Open Editor Window” command from within Glass, which opens a classic-mode window where Dev Containers work as expected.
The team is actively building out remote support in Glass, starting with SSH. I don’t have a specific timeline for Dev Container support, but your report helps prioritize it.
You may also find this related thread helpful, where the same pattern was confirmed for WSL: Glass Interface doesn’t work with WSL
