Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the detailed report with the video and version. This is a known bug in the Agents Window in Glass. The Left and Right arrow keys sometimes stop moving the cursor in the input field, while everything works fine in the regular IDE editor. We’re already tracking the issue, but I can’t share an exact ETA for a fix yet.

As a temporary workaround, try Reload Window with Cmd+Shift+R or restart Cursor. Arrow key navigation should work again. This bug is intermittent, so it might come back later. If it does, just reload again.

I’ll post an update in the thread once there’s news on the fix.

So I actually experience this consistently, and Cmd+Shift+R doesn’t fix the issue
