Perhaps I am doing somethng worng, but when XPlode run then executes the program to install, Xplode takes up the entire processor and doesn't allow the installation application to run at full speed. It took Office 2003 2 hours to install. Here is how I am running XPlode. <within a batch file> %CD2%\install\Xplode.exe I can execute XPlode as a "Low" priority by using the following START /LOW %CD2%\install\Xplode.exe However, everything that spawns from that process is also set to LOW. Any ideas?
