For those using Bob's new Jig addon, please note that as Bill pointed out, the addon directory name inadvertently used upper case, whereas lower case is required for cross platform compatibility. I should have checked this in the addon builder.
I will now delete the original addon and commit a new version. This should not affect what you have already installed. However, the package manager will show Jig as not yet installed, so to update it, just install it again. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
