I'll have to experiment. Problem is, each program that prints may or may not have the print dialog. Also, they may or may not work in different ways... Let me have a play with that.
I've changed it now so it doesn't minimise.
There is a simple scheduler, that allows you to schedule it to run in a given number of mins, hours, days or weeks. And, to set it to reoccur after that given time (i.e. run the check every 12 hours). Its a little crude, but works and avoids having to use the Windows scheduler.
The main problem at the moment is the print dialog you have coming up, none of my apps that are being printed through have come up with a print dialog! So, I'm trying to recreate it at the moment so I can try and get round it for you.
I won't bother uploading an update yet, as the scheduler is only 90% complete, may as well wait until it is finished.
Also, the "The operation has completed successfully" is puzzling as its not the app showing it! It did happen once with me, but as I said, it was just the first time it
