I purchased and installed SIW version 2015.10.30 on Windows 10. It partially works, but when the Please wait message appears it stays there for a long time - several minutes - and SIW won't close. Only the minimize and and restore buttons work. After it finally closes, the programs, such as Thunderbird, do not respond. If I click on the "Ask me anything" task bar I get a message that Display driver has stopped responding but has recovered and then windows works. This behaviour isn't exactly consistent.
