We had a security breach and some things were messed up on our Ubuntu servers. Now, when I log in to two of our servers using WinSCP and I double-click on a file to open it with my default application, WinSCP instead attempts to open it as a directory, which fails and I get an error message saying "Error listing directory" (of course, because it's not a directory...).
I can still edit the file by right-clicking and choosing "Edit", but that's a bit of a pain to do every time I open a file. I am fairly certain that this isn't an issue with WinSCP at all, since another of our servers which wasn't broken into still behaves properly in WinSCP. But I don't know what settings could be changed in the Ubuntu servers that would cause this behavior. Anyone have any suggestions? We are running Ubuntu Server 9.04 (Jaunty).
Please keep in mind that I'm pretty much a UNIX noob, so please use small words :-)
