Stable version (5.3.1184.31)

[Maks7320]

In the new version 5.3.1184.25, I found another two problems on Windows 7. These problems only appear if I do a clean install of the new version. If I just update from the previous version, everything is fine.
The issues during a clean install:
1. It takes 4 attempts to set Cent Browser as the default browser.
2. When it is finally set as default, Windows still shows Internet Explorer icons for saved bookmarks on the desktop. It feels like the browser is only partially default.
However, if I roll back to the previous version 5.2.1168.83, everything works fine again. Please check this.
