Not always a problem. Except when I’ve got international characters in my filenames. Which seems to be quite common with the import albums I’m downloading.
Dang. There is a patcharound, but it’s unsupported. Honestly, this backwards compatibility is a pain in the ass.
The next issue is cygwin/X. It’s hanging on Vista. Seems to be related to dwm and the pretty aero effects and the occasional toggle to non-aero mode caused by some applications (not java 1.6, though).
