Labs won't start after clicking Start Lab in Chrome (Pop-up blocker)
If you click Start Lab and a loading window does not appear, it is almost always due to a pop-up blocker.
- Click Start Lab.
- Click the Pop-up blocked icon in the top-right area of the address bar.
- Click Always allow pop-ups from this site and then click Done.
- Click Stop waiting for the simulation window to open.
- Click Start Lab again.
The simulation window should then open and begin loading the lab. If it does not, completely close Chrome and repeat the process.
