we hadn’t really considered the need to copy a set of entries from one week to the next. The primary idea of Klok is to capture actual times spent rather than expected times. That said, it is possible that for weekly/daily meetings, the times are all the same. We will add it as a future feature request.
As far as the issues with the display, there was a bug in 1.x that caused problems in weeks that spanned two months resulting in the display issue. That has been fixed in version 2.0 (download the beta at http://klok.mcgraphix.com/klok/betaProgram.htm)
