PointerSnapTo Portable Version
The portable version is for advanced users.
This version doesn't contain an install routine and is portable. Download PSTportable.zip, unzip and run it. To un-install, delete the files in the PST directory.
All settings are saved in pointersnapto.ini which will be located in the same directory as PointerSnapTo.exe. (Which of course implies you must put the program in a directory that is writable.)
If you can't view the help file, right click on the help file, (PointerSnapTo.chm) select properties, then click "Unblock".
