I want to echo the very slow execution of .1267. You said you could not replicate the problem, so here is the information I have. I'm running 2 systems, a 4 core AMD Athlon with 8 GB RAM running Windows 7 Home 64 bit, and a 2 core older AMD Athlon with 4 GB RAM running Windows 7 Home 32 bit. On the 64 bit OS, jv16 runs fine, very similar to jv16 2012. On the 32 bit dual core, it takes forever. The Task Manager will pop up saying that "this program appears to be frozen" it takes so long, and then it takes at least as long after the popup to actually finish and report back. I've tried both Fix and Delete options, and they seem to be equally slow. I think the 32 bit vs. 64 bit OS may be the problem, or at least a clue.
I hope this helps. I've used jv16 back to floppy disk days and have always liked it.
