"d.vect display=attr" imply grass open process but doesn't close them.

[met]

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'
