Can't open Downloaded Files....
 

I just downloaded & installed LW 1.8 (Mac OS 9.1). I can't open ANY of the downloads. When I 2x click LW reopens. I tried using Stuffit to open the .sit files to no avail. I've also noticed that LW's icons don't appear correctly either. Perhaps they're related (rebuilding Dsktp didn't help there)? Never had this prob w/ 1.7 any ideas? Thanks
