LW doesn't create a new folder every time it is launched unless the default incomplete folder is missing. When you set up the LW dwnld folder (as in Tools-Options & Saving) for the final dwnlded files, LW creates an incomplete folder. If you attempt to manually rename, move or delete this incomplete folder, then it could cause LW some problems & probably its defensive action is to re-create the folder. Adjusting the incomplete folder's name (& possibly icon) 'might' have the same effect. Renaming, moving or deleting the dwnld folder would have the same wffect as above. As for changing the view settings of the folder, I'd guess that is more-so os related! It certainly doesn't happen on mac os's.

Under View in Windows, did you use the Customize this folder... wizard or do it manually. The previous might be better. This would aply to either the Incomplete or LW Dwnld folder.
