Sounds like your system's settings are up the putt! Try this version: LimeWire cvs builds (4.13.4jum490) no installation necessary. Just drag & drop.

BTW Sorry for late response.

OH oops upon re-reading you have already installed the program. So what you are doing is clicking the installer again. Move the installer off the desktop. Use the Go menu & choose applications. Then find LW. Then open the folder & drag & drop the program icon into the dock. The click on the LW icon in dock to open.
