Tortoise CVS Command Line Strips Filename Argument?

Sorry if this is not the right place for Tortoise quesitons. If not,
please let me know where to go.
It seems every time I use the command line dialog in tortoise cvs,
It strips out my file argument. For example, if I type:
remove -f filename.binary
Into the tortoise command dialog
Tortoise cvs will execute:
remove -f
This is when I right click on a folder space (right hand panel in
windows exporer) and then select CVS->Command... from the context
menu. I need to do this to remove binaries because tortoise doesn't
provide the CVS context menu when selecting version controlled
binaries.  I used Win CVS without a problem.

Thanks,
