Hello!
Maxthon v7.5.2.6000 (64-bit) 0316 07:29.
Download manager: there's no indicator for the lower right corner to show the box may be resided & although one can widen from the right, one can't extend the length without using the lower right corner.
When opening a folder for a downloaded file & renaming that file, the download manager still shows the old file name, in bold, which is no longer present (unlike v7.5.2.5800 & earlier).
Massive surprise (not!), but the 'new' download manager still shows duplicate entries, which aren't removed when clearing the list, but aren't present upon restarting Maxthon, as ever (been doing this since Maxthon v6), confirming a caching issue
