One I'm sure I got working, but seems to have gone backwards.. I have a document library with many PDF documents, where they open them in Adobe Reader X (Client), not the browser.
I have all the normal bits, it's set to Permissive Browser Handling, etc.. Now, when I open my document on my Windows 7 machine, everything works as expected, it opens in the client, checks out/in, etc. When I open the same document on my Citrix desktop, it opens in the browser - and 'Edit Document' on the ribbon is greyed out.
Both desktops have Adobe Reader X, but one works and the other doesn't! Does anyone have any ideas??
