I think that's what it's supposed to do. The amazing thing is that it didn't used too. Another possibility is that you've upgraded your system so it's no longer fully compatible... a lot of people think their old CS stuff will just keep running as Windows 10 changes.
I'm using Windows 8.1, and I tested other Adobe softwares from the same CS3 suite. After Effects and Illustrator runs at 200 thousand K memory both.
Though, shortly after this bloat occurs, I notice that my laptop is laggy.
It starts up slow, and logs in slow. It also starts up various softwares slowly, and it's acting like it's constantly low on memory despite no program running. I've not changed anything, I've previously cleared all the softwares that might auto-run during startup.
So I'm not sure if the Photoshop crash is what's making the computer laggy, or if the laggy computer is what's bloating Photoshop.
Moving this discussion to the Photoshop forum.
