in reply to File::CounterFile problems and hashes

you should be locking and unlocking the File::CounterFile object, not the class.

## File::CounterFile->lock(); ## should be $counter->lock(); $counter->inc; ## File::CounterFIle->unlock(); ## should be $counter->unlock();

i haven't tested, but this looks like the likely problem. the error message stems from the fact that a File::CounterFile object is a blessed hash reference, so perl is trying to use the string 'File::CounterFlie' as a reference to the object (a hash reference.)
