I just had a problem and wondered if anyone else had seen it or had any thoughts.

I run YzDock 083. I went to the multiplayer page and downloaded the update as I have done before without trouble. This time it crashed saying it couldn't delete LFS.EXE. Unlocker said it couldn't help, it wasn't until I poked around with Process Explorer that I discovered that YzDock had it locked. I closed YzDock and everything went fine when I ran the Version Y installer.

Has anyone else experienced anything similar and come across a better answer than turning off YzDock?
