Hi, back after working with it this weekend. Got some fairly good shots on Saturday and then went at it yesterday and all of a sudden, when I took pics Sat, the quick preview would come right up with the picture I took for examination. Sunday, before taking first pic, the "Live view shooting" tab was white in color when starting up, but right after I took the first picture, it went dull in color and it was not available to click, and no preview. Not sure what setting could be causing it. Also, because it is a canon utility, and I am using a Tamron macro lens, it is not suppose to but I think that could be a conflict in some cases but not sure. As far as computer, it is state of the art with solid state drives running in raid with 16 GB's of memory. It boots Windows 7 in 10 seconds. Have tried several cables all with the same results.
