Dialog may appear differently depending on Windows style options and where it occurs.
During last optimization RWIN = 1052508160 was set. But SyAnalyzer has reported that current RWIN is 17444. It could be because of the following reason:
To set RWIN > 64 KBytes TCP options "Windows Scaling" and "Selective Acknowledges" both should be ON.
Possibly you are connected to the Internet through FireWall or Proxy, which overrides your RWIN value. If it is so, try to change settings of your FireWall or Proxy, otherwise you will not be able to use RWIN bigger than your current RWIN value.
Your system probably has a problem with setting RWIN > 64 KBytes.
