1) click STAR (bookmarks) -- > from drop down bookmark list choose any bookmarked file or folder (A) and drag it to another (any) folder (B). This folder (B) supposed to open (and show all content) , but last couple of months it doesnt (most time) . Yes, bookmarked (A) will be placed in folder (B) at the end of the list, but yuo dnt see content of folder B. Also, when you release pressed mouse left button , only moved file/folder (A) will be seen in folder B. You need to click again on STAR (bookmarks) and now you will see all content of folder B (with file/folder A at the end of list). Happens not 100%, but most time.
2) after updating to Version6.1.3.1200 , youtube doesnt work correctly. No autoplay, you need to click "play" every time (even in watchlist). Cant update to newer version ("update" function doesnt update with every MX update :)) . Only once in 2-3 updates
