Some comments:
Distributing shortcuts isn't good, as those are Windows-specific and as they point so something on your computer. The shortcut is set to start in "C:\Documents and Settings\Mitch\Desktop\Mitch's D2 Runeword Calculator", which most users won't have. Messy.
Distributing thumbs.db files is worse.
Distributing a JAR file with a thumbs.db file is even worse than that.
Glaringly bright background = not pretty.
Grief is spelled wrong.
The alignment of the columns shifts slightly if you go from all haves to at least one have-not (and vice versa).
Holy Thunder requires clvl 24, not 21 (due to the holy shock skill bonus).
The compute button seems somewhat superfluous, as the list could just be updated on every click without significant slowdown.
The layout of the runes seems counterintuitive. They line up nicely in columns, but the ordering is row-first.
The AS has many inaccuracies with the various realms-only runewords. Take any information regarding those with a grain of salt. Unfortunately, because of their realms-only status, I can't give the accurate stats.
It's disconcerting how the runeword description resizes and moves around every time.
Possible future features:
Right now, the options are "may include this rune" and "may not include this rune." You could also add "must include this rune." Someone might have a specific rare rune and want to know what can be done with it.
Buttons to select all and select none.
Restrictions based on item type and number of sockets.
