If you have more than one VFP session, I strongly suggest that you open them with different config.fpw, Personally I use a directory c:\foxjob, with subdirectories, like c:\foxjob\win1, c:\foxjob\win2, c:\foxjob\win3 and so forth. I also have sudirectories under these directories called temp. In each of these winx directories I have config.fpw which I specify by the -C command line switch in the properties of the different icons. So for my "VFP1" icon, I have this in the Target field:

C:\VFP9\vfp9.exe -T  -cc:\foxjob\win1\config.fpw c:\foxjobb\windows\startup

This is the contents of c:\foxjob\win1\config.fpw:

ODOMETER          = 100
RESOURCE=C:\FOXJOBB\win1\FOXUSER.DBF
OVERLAY=c:\FOXJOBB\win1\ OVERWRITE
EDITWORK=c:\FOXJOBB\win1\temp
SORTWORK=c:\FOXJOBB\win1\temp
PROGWORK=c:\FOXJOBB\win1\temp
TMPFILES=c:\FOXJOBB\win1\temp

A few of these settings may not be necessary anymore, but I have used these files for more than a decade now, without any change.
By adding different values for Odometer, I am able to distinguish which config file I start with, in my startup I have a lot of setup code, one line is something like _vfp.caption = 'Visual FoxPro 9 session no. ' + transform(set('odometer')/100)).
