Version 7.5.2.1001 (64-bit) 0909 20:47
This new version of Maxthon seems to have problems with opening websites in Retro mode.
I have a few URLs bookmarked with Retro mode, and now I can't open them from the bookmarks / favorites anymore. When I click on the bookmark, nothing happens. Actually nothing happens even if I type it in the address bar.
For example, take a random website like https://supra-space.com/main/index
If you go to this website in Ultra mode and then try to change to Retro mode, you will get an error ("Aw, Snap!"). If you then close the tab and try to open this URL again, nothing will happen. (EDIT: I later realized the workaround to getting the URL to open again is to use "open in new tab". Then you have a chance to set the core back to Ultra).
If you try to switch core to Retro it in Incognito mode, then Maxthon will crash with a gray screen and 100% CPU load.
