I've been having a lot of trouble with my spells and mob agro lately. I couldn't figure it out. I've tried everything except wiping my folders completely and starting over. Today I tried opening a map file to see what was in the file and access was denied. Then it hit me, my maps were downloaded and extracted on an admin account (windows 2k) and I play on a non admin account. So I went to the admin account and checked and sure enough, the files themselves were set to only have admin access. I reset the folder and all child objects to be accessible by all users and logged onto my nonadmin account and everything works perfectly now. If you keep getting "your spell is interupted" and "you cannot see your target" messages, this could part of your problem
