Hi gtothem,
I am really loving this tool, mostly because it actually works when so many others just suck these days.
I woke up this morning to an issue with the update window. I could not see the little modal window for updating, I knew it was there because its the only thing that could have really caused what was happening (I am a developer, I have run into this before.)
Because the window was up, but somehow hidden behind the main window I could not click on it and I also could not click on the main window to minimize it and get it out of my way. This left me with the software still running, but unable to click on anything or do anything else. I had to use task manager to close it, then re-open and update.
