Charname's actions overridden by AI scripts

Hiya!

I have this annoying issue, which I think was already raised numerous times on the forums: the AI scripts override player-appointed actions for my Charname. HOWEVER, what makes my issue somehow unique, is that it happens only for Charname, and nobody else.

So, say, my party walks through an area and an NPC (other than Charname) is attacked by a pack of gibberlings. All party members use the Standard Attack script, and all ignore attacking critters, continuing on their path... EXCEPT for Charname, who immediately stops and starts attacking the gibberlings.

Similarly for casting spells, I can, for example, order Charname and two mages to start casting. The mages cast their spells just fine, but Charname almost always stops mid-cast and resort to attacking with melee.

I tried different scripts and it happens for EVERY SINGLE ONE (except for "none"), even when the script prevents the character from attacking - in that case my Charname will just stop walking/casting and just idly stand in one place. Even Advanced AI, with all the options disable, interrupts player-appointed actions.

I use mega-installation EET, so I know I will likely never find what is causing this. But I have a small hope that maybe someone, somewhere, encountered such a problem. Any thoughts?
