Hello Nicolas,
That's an old bug - I had it several times last year, never reported it though. Please open a bugzilla bug.
Might you remember bug #s where this happened to you? So I can verify them and add them to the bug report. TIA.
And to Mike, no, this is not a browser bug. How would my browser come up with AfterSteps-APPS? Plus verified in mozilla and konqueror.
Bye, Leonard.
