The first thing that I would recommend is upgrading (if possible); the
version of LAM that you have is *extremely* old. Many bug fixes and
improvements have been included in LAM since 6.5.4 (note that 6.5.9 is the
last stable release of the 6.5 series). Indeed, we no longer formally
support the 6.5 series -- I haven't looked at 6.5.4 in several years.
The current version is 7.0.6.
Can you upgrade and see if this fixes your problem?
