I've just submitted v1.4.5 of "Remember Me" to the Zen Cart plugins; it will be available here for download once reviewed.

This release contains changes associated with the following GitHub issues:

#10: Correct gzuncompress log-generation (cookies have been deleted).
#11: Disable processing when COWOA/guest checkout is active.

Thanks to @solo_400, @mikebr and @davewest for their help in identifying the problem (and its source) and testing the corrections.
