Paul Thurrott wrote in his WindowsITPro newsletter :
Adobe has informed its customers that they will need to pay for new versions of many of its products if they expect to run them glitch- free on Windows Vista. The reason? Adobe has no plans to ensure that its currently shipping products work properly with Microsoft's new OS.
If you're searching for an example of a wrong way to do things look at how Adobe products support Windows Vista.
Before you spend you money for a new version of an Adobe Product why don't you look at the competition.
