Hope this helps Helen :) if you have 2 running ...Disable the pepperflash
Unfortunately it didn't help me with the space bar issue , but might be worth a look to see if you have more than 1 running
Enable or disable Adobe Flash Player
These instructions apply to Google Chrome on Windows, Mac, Linux and Chrome OS.
- Type
chrome:plugins
in the address bar to open the Plug-ins page.
- On the Plug-ins page that appears, find the "Flash" listing.
- To enable Adobe Flash Player, click the Enable link under its name.
- To disable Adobe Flash Player completely, click the Disable link under its name.
Note: If you've previously installed Adobe Flash Player separately, you'll see two files listed for the plug-in. If both are listed as enabled, the version bundled with Chrome will be used. To enable a specific version of Adobe Flash Player, click Details in the upper-right corner of the page. Then click the Enable link for the version of Adobe Flash Player you want to enable.
