i have been using this a long time now to show/hide a texture if my earthshield buff is not active on anyone in the raid, the only problem i have with this is it is sometimes not updating if i overwrite someone elses earthshield, i believe this propably has something to do with some event missing for update or some problem in the basic set engine. maybe you can look into it sigg, but you should put it somewhere onto the list of 1000000 things with very low priority ;) |
