1) Not as far as i know. Maybe someone with a second ed rule book will be able to say otherwise, but I think its just general weirdness. Or maybe you added a weapon proficiency and that improved your thaco or something.

2) Melee weapons appear to attack far more often than they actualy do, since having a fighter stand still 90% of the time looks really naff. If you turn on the extra combat text you can see the acutal attacks come up in the text window at the bottom of the screen and get a more accurate impression.

Oh, and your maximum hit rate should be 95% since a one always fails to hit and the dice is a d20.
