Hi everyone Those of us who use Google Chrome to play iSketch may have change browsers in the near future due to a plugin being deprecated later this year. Chrome, like many other web browsers, uses NPAPI (Netscape Plugin Application Programming Interface) to allow Shockwave to be run on Chrome, which can then be installed to play iSketch. According to those behind Google Chrome, this NPAPI plugin will be automatically blocked for general use from April, and then cease to be updated altogether from September 2015, apparently due to security reasons. If you wish to read the full article, you can find it here. From April to September, a temporary override is available to prevent this automatic NPAPI block, simply follow these instructions: Type chrome://flags/#enable-npapi into the address bar. Locate the "Enable NPAPI" header and click "Enable". Restart your browser to make the changes come into effect. You should then be able to reload iSketch without the usual "please install Shockwave" screen. I hope this helps Here is a Wikipedia list of browsers that still support NPAPI. Update: As it currently stands after September 2015, iSketch will not work for any players using Google Chrome. Instead use one of the listed browsers.
