(I know I can create it on a different computer by manipulating the component properties in the control panel, but I want to sta...

Problem is that I use a 5.2 Sitecore, and when I start to publish something, it only shows the publishing window and a "Queued" message. There is a chance that some people full published several times(that means 15000 items and 4 slaves), and the publishing queue is stuck. The restart of the webserver/app pool is not an option.
