I had the trial 1.02 and bought 1.03. You really have a great thing here!
I noticed the uninstaller for 1.02 said to "close start8" before uninstalling, but there isn't an obvious way to do that. I stopped the service, then killed the process, but the start8 menu still worked for some reason. anyway, the uninstall seemed to work, and I rebooted before installing 1.03. that method seems to work fine, although it may be true that people will want a more intuitive installer/uninstaller.
Also, it seems that 1.03 fixed an issue i had with multiple monitors before i could even tell you about it. basically the "windows 8" style wast not working, but now it is. I plan to use the win7 style for now though.
