Right now just simply copy the DueToday.exe file to your thumb drive and it has code in it to detect this and set things up properly.
As for sync issues, there shouldn't be any because it syncs to the appropriate server just as any other client would.
Umm, I suppose you don't mean the .exe file you can download from your web, but the DueToday.exe file usually installed in C:\Program Files (or similar).
I tried that this morning, I can run the program, but when trying to sync (via Toodledo), I got an error (my main interest is to be able to use it at my office PC, since I haven't got admin permission to install it there. I haven't got IT lockdown issues in accessing Toodledo, so I guess that shouldn't be the problem. Am I wrong?
Thanks again, in advance, for your time and effort, ;-)
