Fix for automatic folder expansion in computer node

[psychoadept]

When I drag & drop to a folder in the computer node, it often expands to show the subfolders just as I release the button, resulting in the tracks going to the wrong folder because the location of the parent folder in the sidebar changes. Either there needs to be a fix so the parent folder doesn't move when subfolders are shown, or I would like to be able to turn off expansion of folders until I manually click the triangle.

for the next 3.4 update i have bumped up the hover delay before expanding the folders automatically

Ok, thanks. I'll see how that does.
