About cvs sticky tag

[Jillfox]

Excuse me,Can i ask you some question?
When i use cvs to control revision for a project,i found that a sticky tag named 1.4

 

bash-2.04# cvs status -v driver.cpp
===================================================================
File: driver.cpp        Status: Locally Modified

 

   Working revision:    1.4
   Repository revision: 1.4     /usr/local/cvsroot/C_S/driver.cpp,v
   Sticky Tag:          1.4
   Sticky Date:         (none)
   Sticky Options:      (none)

 

There cause that i can't commit the modified file

 

bash-2.04# cvs commit -m "Litter function" driver.cpp
cvs server: sticky tag `1.4' for file `driver.cpp' is not a branch
cvs [server aborted]: correct above errors first!

 

How can i do for it?How can i delete the tag?
