try this (save as an AHK).
Code:
#NoEnv
#SingleInstance, Force
Loop
{
Process, Exist, PartyGaming.exe
if (ErrorLevel)
{
Process, Priority, %ErrorLevel%, H
}
Sleep, 60000
}
lol - I can't remember the bat file or shortcut thing accurately
This will check every minute for a partygaming, if so - set it to high
