I downloaded an extension, PSKiss Photogram for Photoshop CS5. I have successfully installed it through Extension Manager where I can see it is installed. I also have checked in the Program Files (x86)>Adobe>CS5ServiceManager>extensions and it is present there as well. However, when I open up Photoshop CS5 and go to Window, the Extension menu is grayed out and nothing is present or even available for me to click on. I have tried many things but I can't seem to get it to work.
I did try uninstalling and I do not seem to have any other default Extensions. I have never used extensions before so I don't know if I am missing something but Bridge and photoshop show in the extensions manager and no other extensions are listed.
This post made me interested in looking at the extension.
Their web site colour scheme makes the site almost unreadable - there is extremely poor contrast between text colour and background colour.
I enlarged the text and was then able to read it of a fashion.
I know my eyesight is not necessarily the best but it really frustrates me that web designers are so obsessed with "trendy" design that they forget the basic need of a web site to be readable (particularly if it is a commercial site).
I have also sent them a message directly about this.
OK - now I will jump down off my soapbox !!
