Mike,
Just loaded 7.0.50 onto a Windows 7 32-bit machine, and it returns a script error on line 32, looking for a file in …\skins\interface\splendid2\cache. The cache directory does not exist under splendid2. Window opened with just a border and no data. Task Manager was needed to close that window and will not reopen without rebooting. Icon shows in notification tray and will display current wx conditions when hovered over.
