Please see the image - I cannot scroll any further down the keyword list after the word 'coloured'. This is a much more recent problem than the separate keyword export issue I have just reported but it means that I cannot do even a manual fix of that other issue.Help much appreciated!Scott

LR also chokes when there are more than about 1500 folders in the Folders panel or 1500 collections in the Collections panel. The original sin here was Adobe's.

Every
 Windows application with large scrolling lists  has to cope with the maximum size that Windows imposes on low-level windows (32K pixels) by repainting the windows as necessary. Most applications do that by using commonly available libraries of user-interface controls that do the work for them. 

But Adobe took a shortcut when they implemented LR Windows, choosing to implement their own controls but failing to complete the work. They did it for Library grid view but not Folders, Collections, Keyword List, and other panels. And they've never owned up to taking that shortcut.  See here for details:
