target out of range

ok , this has been happening for 2 days , occasionaly at first , now with every monster i fight .
i target a monster , but if i move at all , and only get "target out of range" from that point on if i try to use and attack spell , and sometimes even if i dont move it keeps telling me the target is out of range .

now this happens on my whm , if i switch to my bm and fight same mobs in same place , its fine , everything works , switch back to whm and same targeting problem exists.

this has now left my whm completely unplayable , and as this is my main char , is a major issue for me .

the char name is Miss Chevious , world is cerebris

Did you recently turn off the setting to automatically face your target?

Character Configuration menu (K)
Control Settings menu along the left
Target tab along the top
"Automatically fact target when using action" check box second from top

was tinkering with those lol , set back to default , seems to be working fine .

thank you very much for the quick reply and help , couldnt figure it out haha .

thank you again.
