This is a known issue in build 178.  It has since been corrected, in build 197.  I am a customer running the current licensed production version 206, and can confirm that this problem no longer exists as of 206.

Logsat's method of producing "trial" versions differs from most other software vendors.  Most vendors provide crippleware or expireware for evaluation purposes; Logsat, on the other hand, provides functional (non-crippled, non-expiring) trial software that's just a little older than the current licensed release.  As a result, the trial does not contain all of the latest features and bug fixes as the licensed release.  The release log http://www.logsat.com/sfi-release-notes-and-bug-fixes.asp" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - http://www.logsat.com/sfi-release-notes-and-bug-fixes.asp" CLASS="ASPForums" TITLE="WARNING: URL created by poster. - http://www.logsat.com/sfi-release-notes-and-bug-fixes.asp  might prove helpful in your evaluation.
