I installed local 6.4.3. in Windows 7.
I suggest to add this property to your software:
If we minimize (or close x) the local window, I like it goes to down right in tray section. So to exit local one should right click on local icon in tray section and click “exit”.
Since it takes some space in taskbar.
To be more clear I suggest you to look at Mozilla Thunderbird or Skype. they have such properties.
