Thanks for your quick response Jan,
I did as you said...downloaded the attachment herein and replaced the "do.exe" file of my FARR portable folder with this one, then tryed to create the following task (taken from one of your examples):
"do Mow lawn /due sat /cat house /totalwork 2"
After this, the following message appeared: "No task or appointment seleted" (please check the file attached). I don't know if actually matters, but I am on WIN 7 and Outlook 2010 running a portable version of FARR from my flash drive.
Thanks in advance for your help, I really appreciate it!
