Hi Peter,

we had a similar problem a few years ago with a standalone FP 2.6 application under Win98 (no Novell). The environment is quite different to the one you discribed, but the corrupted tables looked exactly like yours.

Usually the corruption occured in the morning, while a stack of bills where calculated and printed, but I don't recall whether there always had to be midnight between the last successful writing process and the one that raised the problem. We never found the cause of that problem, though it disappeared after implementing a periodical (once a week) deletion und rebuilding of the index files.
