Thanks to all that responded, As it turned out the problem was with the Graphics Controller on my Dell, I downloaded a new one from Intel and everything is spinning in greased grooves. Hank my local rep came up with the fix, here is his response that explains what to do: In several cases of Allegro's "disappearing graphics when zoomed far in," the problem was with Dell computers with Intel 82845G GL Graphic controllers; in these cases downloading the Intel 828445G/GL/PE/GV Graphics Controller and reloading the driver resolved the problem. The driver can be found at: http://downloadfinder.intel.com/scripts-df/Product_Filter.asp?ProductID=865 In at least one other case, the source of the problem was the video driver for an nVidea graphics card that was obtained from the Dell website. The customer downloaded the latest driver directly from NVidea and that resolved the problem.

I haven't seen this since 14 and figured it was something in my setup also. I never found a way to make it stop. But since I went to 15.1 I have not seen it. I guess it is still there and you have it now. We Allegro users like to spread the wealth around. Your turn! If you find a way to fix it please post.
