Do you mean the window is really minimized (as in open, on the taskbar, still showing the folder, but minimised via the \_\_ button), or that no windows are open?

Could you have a look at the change events Opus is receiving to see if there's anything unusual there? The _Debugging_ section near the bottom of this post has instructions: [Changes to folders are not being detected](https://resource.dopus.com/t/changes-to-folders-are-not-being-detected/1786)

Making a few process snapshots while the CPU usage is happening and sending them to us may also reveal something: [Manually generating process snapshots](https://resource.dopus.com/t/manually-generating-process-snapshots/34071)
