I just installed LW Pro 4.0.7 (same problem happened with free version earlier) on to Mac OSX Panther 10.3.4 and despite trying to download with Safari, then Explorer (with full deletions of all LW files and safe booted permission resets in between) and 4 attempts at installation, the program will not launch. The application icon bounces in the dock then vanishes after about 1 minute. Any suggestions?
