groovy script not reloading

hello,

i have a number of groovy scripts which change frequently. sometimes, the changes arent recognised until i do a reload of the whole project despite seeing the following in the soapUI log

Fri Nov 12 15:24:01 EST 2010:INFO:Resetting groovy class cache due to 2 modified files
Fri Nov 12 15:24:01 EST 2010:INFO:Setting Script Library to [C:\project\soapui\scripts]

is there any reason why not all changes are recognised by this auto script refresh?

cheers
toby
