I recompiled the Log Visualizer with Adobe AIR. You can download it here.
I tried it under Windows XP (Parallels) and it seems that the File.browseForOpen doesn’t fire the Event.SELECT event under Windows. So the bug is that you can open a file, but the application doesn’t know when you selected it. I was contacted by Logan today who wanted to know if there is a Windows version. So sorry for the Windows users out there for the moment. Note that the Apollo version of the Log Visualizer was working under windows.
