RM2003'S LINK TO EVENT FAILURE

I searched everywhere but never found a site addressing this issue. I don't know if you guys experience the same in your testing (maybe my copy of RM2k3 is corrupted) but actions I've set to Link to Event type fail all over the place.

For example, I have a Link to Event skill "Observe" which is like FF series "Scan" on enemies. However if I enter a skill subset menu on that hero's turn, cancel out of it, and then select "Observe" (complicated, but it happens) the other two heros on my team freeze, take no action, as if they were afflicted by a stun skill, until the original character chooses another action.

Another such problem is a Link to Event skill "Inhale" which charges up for a powerful attack. I know this is weird, but sometimes either before or after the attack actual, the attack will use used on the enemy but NO ONE CASTS IT. It just gets used out of nowhere. Even weirder, sometimes the enemy will use a skill it doesn't know, one from the inhaling hero's skill set, but it absolutely has something to do with Link to Event.

I set both of these Link to Event skills to Defend type skills, which boosts their defense (didn't intend it, but if it works, I'm not complaining). They both work fine now as defensive skills, but wtf?
