Few things

1.Seems 3.9.6 doesn't come with Log file function?

2.Line-in still not supported in Win7?

3.Always find the events window annoying coz I have to look from the very top down in order to find the right data, I'm sure it will be a lot easier to have a search bar.
Type in 14:00:00 or 2013-4-29, and the cursor jumps right to the point, press F3 to jump to the next result.

4.If using localization, the registry file provided is not working properly in Win7, coz it should be registered under

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\WoLoSoft\Raduga\Languages\]

not

[HKEY_LOCAL_MACHINE\Software\WoLoSoft\Raduga\Languages\]
