Hi

Here are a couple of solutions.

If you have a lot of uploads (watch the monitor pane for activiity, or the Tools->bandwidth-upstream graph), just reduce the slider in the Preferences->uploads to ~85% of your tested speed.

To find out your tested upload speed (when LW is not running), do the speed test at http://www.broadbandreports.com/stest

If LW has been running for a long time, the virtual memory can get high. Open Activity Monitor in your Utilities folder and see if LW's Virtual Memory is about 600-700 MB (usual). If it is larger than about 1 GB, just shut your machine down for a couple of minutes at some convenient time and restart again. That will clear the old memory and get a fresh start.

cheers
