Hi

Some users have been experiencing problems when running Limewire together with other applications (the operation of the other applications being interrupted by the spinning coloured wheel or grinding to a halt). The developers are aware of the problem and we await an upgrade that will resolve any problems with Limewire. However, do not assume it is a Limewire problem. When you accept OSX upgrades, there can be problems with the existing application permissions. So, as a self-help measure, restart your Mac with the Shift key held down, invoking Safe Boot mode. This will cause First Aid (also known as fsck, or file system check) to be run (invisibly, but it is being run). (Restart again immediately, in the normal way, after doing this.) If that does not improve performance, run Repair Permissions in the First Aid Panel in Disk Utility (located in your Utilities folder.) There are other things to check, but let's start with the easiest first.
