FAQ
Reader questions
Why does Chrome 2018 keep saying shockwave flash isn't responding?
Chrome 2018 blocks outdated Shockwave Flash content by default and requires explicit user permission or enterprise policy to run, which leads to the not responding state when sites attempt to load the plugin without approval.
Can I still use Shockwave Flash sites in Chrome 2018?
Yes, but you must click the shield icon or adjust site settings to allow Flash on a case-by-case basis until the plugin is fully removed from the browser.
Is Shockwave Flash safe to enable for legacy internal applications?
Enabling Shockwave Flash for internal legacy apps is possible via enterprise policies, yet it is recommended to modernize those applications to avoid security vulnerabilities and browser compatibility issues.
What should I do if my eLearning content still relies on Flash?
Convert eLearning modules to HTML5 or compatible authoring tools, and use enterprise policies only as a short-term workaround while migration is planned and executed.
