[AccessD] Attach to Front End

Hey All
I have a program that allows a user (from the Front End Main program 
menu) to reattach "on the fly" to different data sets located in 
different project folders located  on their local machine and/or on the 
network. There is a standard Back End  mdb that resides in each folder 
and is used to record information for each project.  In my testing the 
reattach "on the fly " everything seems to be working fine.  My question 
is has anyone experienced any problems with reattaching to different  
Back Ends while remaining in the Front End.
