JavaScript Differences Between Lotus Notes 6.x And Lotus Notes 7.x

Lotus Notes 6.x:
navigator.appName => „Lotus Notes“
Lotus Notes 7.x:
navigator.appName => „IBM Lotus Notes“
If you use JavaScript in Lotus Notes to distinguish bt. Notes Client and Browser this code will not work anymore.
navigator.appName != „Lotus Notes“ => always true in Notes 7.x
Possible Solution:
navigator.appName.indexOf(„Notes“) == -1
