I tested LibreOffice Calc Portable 3.3.0. When I started LOP Calc i got a info to install JRE. But there is Java 6 Update 23 on my system (no portable)!
If a cell is formated for a date in "TT.MM.JJ" format (like "31.12.10") the date is not displayed correctly. It is displayed as "TT.12.JJ". If I change the format to "DD.MM.YY" it displays correctly, but this "user-defined format" is not available in the list of date formats.
With the installed version of LibreOffice the date is displays correctly. So I think it is only a problem of the portable version.
Have anyone a idea?
