--- Comment #3 from Zebediah Figura z.figura12@gmail.com --- Okay, I'm a little confused about what's wrong here. I ran the installer once in a clean prefix, using plain Wine, and the program seemed to install successfully, and launch to a window prompting me to log in. I then ran it again, it successfully detected that it was installed, and uninstalled itself. A third run installed the program anew. This seems to be the functionality I'd expect from a typical installer, although I didn't test on Windows. Is this not the behaviour you're observing?
I presume I need to get past the log-in window to observe the blur you're talking about, and I don't think I have the ability to register for an account, since they seem to be trying to prevent people from using any free mail provider for that purpose.
