Close the sliding alert box
From AzureusWiki
It's been reported that on Linux machines, clicking on any of the buttons the sliding alert box results in no action. The vast amount of these occurrences happened due to an upgrade in GTK+ that uncovered a SWT (the widget library Azureus uses) bug. SWT has since fixed the bug in their code. Until there is a new release of Azureus with the newest SWT version, you have two options:
1) Manually upgrade the SWT libraries in the azureus program dir, which can be downloaded at http://download3.eclipse.org/eclipse/downloads/drops/R-3.2-200606291905/index.php#swt
or
2) Download the latest Azureus snapshot at http://azureus.sourceforge.net/index_CVS.php . At the minimum, you'll be able to press escape to close it.
