The spring loaded folder feature is designed to allow folders in Inventory to "spring open" when dragging an item into that folder. This allows the item to be placed into the folder or a sub-folder within that folder. HOWEVER, this feature suffers from an awful bug that seems designed to make users as angry as possible. Unlike other systems (e.g. Windows and Mac OS X native folders), the SL spring-loading does NOT keep the current target folder under the mouse when it opens. Instead, as the folder springs open, the inventory windows scrolls in a more-or-less unpredicatable way. Of course, 4 times out of 5, this happens at the instant you drop your inventory item, and this results in the item being dropped into the wrong, and totally unknown, folder. Steps to repro: 1. Begin dragging an inventory item. 2. Drag it over a "closed" folder. 3. Wait for the folder to spring open. 4. Notice how the folder you positioned the item over has moved and you are now holding the item over a totally different location. If the spring-loaded open happens just as you drop the item, you are hosed; the item has vanished into an unknown folder. Fixes: 1. Hack. Make the spring-loading delay longer, so that it's less likely to happen. 2. Correct: Fix the scroll logic in the inventory window so that spring-loading keeps the current folder under the cursor when it opens.
