You want to watch 64,000,000 array elements :?
Don't you think it might be a little time consuming to scroll through all 64 million elements? What are you trying to find in that haystack? This is a very ineffective way to debug a program. Why not try to add some code that detects the conditions you are looking for, assign breakpoints to those conditions, and create variables that summarize the relevant subset of the data. This will be much easier to watch in the debugger.
