Problem with Microsoft zip extractor and Kepler zip
The nightly build of Kepler creates a nightly zip file that contains all the code needed to run kepler from a shell/batch file. The zip file is quite large (~100MB). WinZip handles extraction of the zipped files nicely, but if one uses Microsoft's built in zip extractor, IT TAKES FOREVER (if it works at all!). The Microsoft zip extractor does seem to work OK for smaller zip files.
Note: This is not a bug in Kepler, but in MS unzip. Mentioned here primarily as a recond of this known problem.
