System Failure when Recompiling with mem_init files

There was a bug in earlier versions of Quartus (or sime bit of the GUI) where, following a re-load of the fpga, it compared against a cached version of the fpga timestamp instead of reading it from the fpga.

That may be still present, and might be confusing things.

Some 'random' mouse clicks would cause it to re-read the timestamp value.

In this cae careful inspection of the timestamp values showed that it had the new value for the code, but the old value for the fpga image.
