If you have a printer installed, and yet Adobe Acrobat refuses to print :
Error : “Before you can perform print-related tasks such as page setup or printing a document, you need to install a printer”
It could be because you don’t have a “default” printer selected. Simply right click on one of your printers and select it as the Default Printer.

Twitter has once again fallen foul of a viral automatic tweet. Although the last outbreak of twifficiency did warn that it would tweet on your behalf (admittedly in small writing initially), this new outbreak relies on jquery to manipulate the Twitter site to tweet on your behalf simply by hovering over an image (cunning!).
