hey buddy, was in a similar banana boat as I find memory will rack up quick.
http://kmext.sourceforge.net/ext7.htm CTRL+F restart just keep an eye on it yourself or do it every hour or when you have an off time and it will resume exactky where you left off only at rest memory having it restart for you may be a bit of pain if you're in the middle of something unless it generated dialouge box.
IF that is your thing you could still download that drop her in the folder and create a script to click that x/y portition of the screen and if in windows run dos output tasklist looking for image name and if matches look at memory and if value generate dialouge and if equal yes click xy cordinate in linux you can even assign a custom pid to images which is wicked
