 Using version 6.4.0 or 6.4.0 RC7 the defect shows up, instead of RC6
 in which not, operative system Windows XP professional.

 When you are using a PAN or ZOOM command, or simply adding a layers,
 (looking from windows taskmanager)map display start a "cmd.exe" process.
 This process disappear after few seconds but if the option display=attr is
 active, doesn't shut down properly:

 -at every zoom/pan on map the Map display open a new cmd.exe process that
 will never be closed.

 -this trend (adding process) go ahead until the Grass doesn't work and
 stop following comand .

 -even closing Grass before or after its block those process don't
 disappear.

 -the only way in which a user could shut down those process is the windows
 task manager.

 example:
 '' d.vect map=reteF display=shape,attr
 > type=point,area,centroid  attrcol='id' ''

Comment(by hamish):

 `dbf.exe`s still piling up in the process manager with latest 6.4.svn
 native wingrass nightly build. what's more if you select disp=attr
 attrcol=label the wxGUI locks up with an endless hourglass. the "this
 program is not responding" dialog helps you kill it and get back to the
 working msys prompt where you can restart it with g.gui. (but the
 `dbf.exe`s remain running)
