First I have to thank hasi001 for the latest WPI, it rocks I only have one single problem left and altough it doesn't really occur that many times in real life it could happen and I'm a little annoyed about that The thing is, say you put your timer on 180 seconds, and then you start the installation after, say 60 seconds. What happens for me is that it starts the installation BUT restarts the RunOnceEx windows after 120 seconds when the timer has run out in the background. The reason why this doesn't happen very often though is that if you select just one program, change anything, then the timer will stop automatically. So there's a pretty simple solution, just that I can't do the coding. The timer needs to be stopped when you press Begin install just like it does when you press the other buttons. Some of you might say that it's not a problem if it installs almost everything again and that's true IF that means it really does it, with that I mean it doesn't interrupt and say you have already installed that application. ( which it did for me ) Hopefully someone got the solution.
