This is driving me crazy, there are some helpfiles in the Addon-Pack (Beta 28.1) that are “shortcuts” and not the actual Helpfiles.
Is it just me or is this a real problem? I tried with Explorer, Winrar and 7-Zip.
In the meantime, I would really like to see the Shift (Spreads Vector) help.v4p helpfile, need a shift with binsize.
