Created attachment 1869 [details] file from event viewer Good evening. Error occured also on previous PC on Windows 7 (so I think we can exclude problem with hardware). By some random amount of time, sometimes few times in an hour, sometimes 2-3 times per whole day Claws just crashes. Without moving his windows, browsing email or anything. I got only description from Event Viewer. If you want me to gather any information please type it, so I will do. Best regards.
