Hi Ishana:
I can't explain those 2 issues but I can suggest a work-around for the first one.
You could edit the shortcut on the user's desktop and add the following to the "Target" field after the name of the program executable: /dM:\Softrak\Data /eDAT (assuming that the data folder = M:\Softrak\Data and the data extension = DAT).
The data paths for each user are stored in the application's INI file. For instance, look at \Softrak\Payables\Payables.ini. If the user logs into Adagio as "IA", look for "[IA]" and IA's historical data paths should be listed.
