I sent this to Maxthon yesterday:
"Yesterday, I d/l'd and installed the latest version of Adobe Flash Player: 11.4.402.287. My Pale Moon and Comodo Dragon Browsers show I have v.287 installed; however, my Maxthon3 browser v3.5.1.800 shows I have Flash Player v 11.4.402.278 installed. Why is that?"
Got this answer:
"Thats the version that comes with Maxthon for use in ultra mode. Using retro mode will use the version you have installed for IE."
Hope this helps. I am running Maxthon (beta) 3.5.1.800
