When I am downloading a fiarly large file the DL will go smoothly till its gets to 99%. Once it reaches that point it can take sometimes up to an hour to finish the DL. Is there a reason y it is taking so long to finish when it gets to that point?

Other people sometimes notice the same issue with particularly large files. Not sure why. It may be something to do with either you or your host's abilities handling the large file. Just guessing. And of course, once it reaches 100%, LW will take a considerable time to verify that the file is identical to the hash tree it inititally downlded when you chose to downld the file. The larger the file, the longer the verification process. I have noticed with large files that the sources tend to drop off once around the 99% mark & also for the verification process. So whilst you may have been downlding from multiple sources, it may drop off to one at that point.
