For no reason all my database will freeze on the Window's Platform but not on the Mac. PC's will lock up every time, with force quit as the only option.

Why? I have replaced the suspected modules with backup versions. Check the scripts. There are no scripts running, it finishes every thing the script is suppose to do but then locks up with the hourglass. I have tested this on different PC and the same problem exists. I have recovered the file. Still no luck.

It would help greatly if you could tell us just exactly what is happening when the freeze occurs. For instance, what is the script that finishes just before freezing?
