I have installed CYGWIN & AFNI version on my lab PC to supplement the hated UNIX. It works OK.
Repeated the procedure on my home PC - similar config (XP, 3Gz, 512 MB, 120 MB).
CYGWIN & X11 start OK. AFNI refuses to with a "Missing Component" error box stating that "cygICE-6.dll" is missing. Yep it is.
Checked with my lab system and it has no such dll loaded, but still works.
What's my problem (other than UNIX).
