I don't know for the latest version of wndowblinds as I uninstalled it after the bugs it exhibited so I am back on V.742.325 but on this one minimizing a rolled windows doesn't work. Maybe worth checking it in W8 even the renmants between changing versions as I'm nerly pretty sure this minimizing issue didn't exist before my transition to the last W8. One example to support that is the W7 -> W8 process left me with my preferences to be rebuil (how about some options to save and recall them ?) and when I went back to W7 my perappskinning was back...
