I decided to test ZCS 7.2.4 as well, on a fresh UBUNTU SERVER 10.04/64bit installation on VMWARE.
I had the same result. I can't preview any file. it isn't possible. should i have to install any package/utility or other stuff to make it run?
I don't know why and can't find any information. anyone can help me?
I'm testing it on a mac os (chrome and firefox), windows xp (ie and firefox), w7 (ie and firefox)
