MX5 PC Beta Release 18.104.22.1680 in Maxthon News Posted 3 August 7 hours ago, stifani said: maintaing 2 different builds with 2 different engines, it's a pain in the ass Why are you trying to maintain 2 different builds? The 5.3.8 series is for testing only and is only betas. If you are not into testing, then just use the 5.2.7 series final version. And just what version of 5.3.8 are you using: install or portable? If you are trying to install both series, you are only asking for trouble.I only use portable versions for betas (actually now use portable for all installations) as they are all inclusive in their folder and don't use the Roaming\Maxthon5 folder for data storage, which both would use if installed. The question I have for them is why are the 5.3.8 series versions available to the general public and not just for testers?
