I'm launching multiple copies of aerender.exe (a command line renderer for Adobe After Effects) using start-process. This renderer produces a truckload of verbiage which is handy to have in order to spot render problems. So rather than use -NonNewWindow I have them all run in separate windows.
Trouble is that if something goes wrong (as it often does) the process quits and the window disappears and I don't know about it unless I go and actually read all the log files #TooMuchLikeWork.
Is there a way of starting a process and leaving the window open after the process quits so I can quickly spot when a render has barfed overnight?
