Disconnect network drive with resource closing

[Statler6]

I have to change drive mappings during build and sometimes it might happen that I get the following message when VBP tries to disconnect a drive mapping:

09.12.10 14:20:52: Building project step 3 - Disconnect Drive...
There are open files and/or incomplete directory searches pending on the connection to Q:.

Is it OK to continue disconnecting and force them closed? (Y/N) [N]: 
No valid response was provided.

http://ss64.com/nt/net_use.html suggests that this can be avoided by using

NET USE [driveletter:] /DELETE /Y

instead of

NET USE [driveletter:] /DELETE

I suggest that the Map Drive action is amended to provide an option for that /Y flag to disconnect network drive.
