ok problem solved...

i'll paint this picture from a pvp standpoint. if you have ever fought a mage who used mirror image, u lose your target on them as part of some trixy blizzard thing. because of this i can only assume it also clears FOCUS, which is the root of all of my macros. therefore after realizing this, i checked on my mages when i casted mirror image, and sure enough they lost their focus, ie my brain, ie their main targeting source. so they were not casting due to loss of focus, so i will change my mirror image to a macro so that it will show /in .3 /focus *brain*. this should solve it w/o me having to remember to push my focus me macro.

sry to waste your time keyclone, and thx for responding, i hope this might help out other mage boxers and possibly those that use focus macros in pvp against mages
