"Mouse doesn't work", what to do depends on what you mean
1. To select text in the ZTree window
Add /M to the commandline, and tick Quickedit on the shortcut
2. Interact with ZTree
Remove /M from the commandline
3. Do you mean mouse wheel?


Check the "3.11 Mouse Functions" and "3.13 Command-Line Options" sections of the help file, press F1, or view ZTW.HLP. There is also a comment in the BETA.TXT file.

Check the "3.14 Auxiliary Files" section of the help file

You will need at least ZTW.INI and ZTW.HST

Depending on your config, one of these directories
The directory with the ZTree exe
The working directory where ZTree is started
%APPDATA%\ZTreeWin
