I've been using group-office for a while now and have had trouble viewing files. It installs and runs fine and at some point (I can't tell why) is no longer able to display uploaded files in the browser window. I either get garbage characters or the temporary file cannot be found on my hard drive. I even just now did a fresh install and was able to view an uploaded file once in Mozilla - the second time it couldn't decode the file. I didn't change a thing in between views.
Any ideas? I have previously changed the filesystem to straight links just to get things to work.
