I've got another issue for the "Windows 10" style menu in Start11.  Using Start11 version 1.39 on Windows 10.

To see what I am talking about:

• Use the "Windows 10" style Start11 menu.
• Size the menu so that it can hold three groups of tiles horizontally.
• Create new groups of tiles until you have about 40 groups.  (It does not matter how many tiles are in each group, just one tile in each group is fine.)  This will result in the menu scrolling vertically.
• Now, try to move one of the groups from further up to the bottom of the menu.  (It's impossible.)

With this many groups, it is impossible to adjust the positions of the tile groups at the bottom.  When dragging tile groups around, the position of the tile group that you are dragging does not track properly with the position of the mouse cursor, so when you get to the bottom you will realize that you'd have to move the mouse cursor off of the bottom of the screen to get the tile groups to move all of the way down there.

Do note that I am talking about moving tile groups and not individual tiles.  Moving individual tiles works fine even if there is a large number of groups.

The workaround is to move a tile group as close to the bottom as possible and then move the groups below it up to sort of finagle things into the right place.

(Display scaling could be impacting this; I am running with a 4K display at 200% scaling.  I tried different tile "sizes" with the "Shortcut icons should be sized:" option, and was able to reproduce the issue with both "Medium" and "Large" size tiles.)
