bigtracked fixed reports not entirely fixed

my question would be what to do if report was marked as fixed, but it was not entirely fixed?

the report i am speaking about is specicifc que on icecrown, it does work at some degree but its still not working as it should be.

should we post another bugtracker and state there what is still wrong with it, or should we leave a comment on the previous post wich was already marked as fixed?
my point is do staff who are in charge of bugtrackers actually read comments on already ,,fixed" bugs?

best way is to open a new report explaing the problem and also that the previus report was flagged as "fixed" but it is still bugged instead
