Hello there OP, This is a great program, thanks for all the effort so far! I've having one small issue with the latest version 2.1.4 and Dropbox (currently v2.2.13 installed). If I right-click on the Dropbox system tray icon the status screen always says 'Connecting..." and "Dropbox is starting...". This happens even if I have "No restrictions" set on the Dropbox executable (by default at C:\Users\<username>\AppData\Roaming\Dropbox\bin\Dropbox.exe) I've tried disabling blocklists and enabling LAN traffic but I'm still seeing this behavior in Dropbox. In TinyWall I'm seeing Blocked connections for Dropbox.exe from (local):50497-50500 to 22.214.171.124:443 over TCP. The only thing that "fixes" this problem is switching TinyWall to Learning mode, Allow outgoing, or Disabled. I am using Windows 7 x64, fairly vanilla system, nothing out of the ordinary on my local network (ASUS router behind U-verse RG). I am able to tracert to that Dropbox destination IP with no problems. Any ideas?
