I finally did the upgrade to Windows 10 on Monday night after jumping through some hoops to get it installed. I had to do it the manual way because the automatic way kept hanging up and would not complete the process. So far so good as far as weather station programs go. I upgraded to the latest version of VWS and it runs fine. However, I keep getting a message on my screen that keeps asking me what program I want to open a file with. The strange part is, I haven't even been trying to open a file. It is getting rather irritating and I cannot figure out what is causing it and how to get it to go away. FYI, I run Fling to take care of all my automatic FTPs for my website. Could it be that Fling is causing the issue?
