Apparently you close the file you wrote, so maybe the problem comes from 
elsewhere.

You can check which files you are really open by using "strace". Enter the 
directory of your project, and type "strace gbx2" (or "strace gbx3" if you use 
Gambas 3). All system calls will be printed, and you can analyze the output to 
see when the open() and close() system calls are used.

You can check too your project, by printing a debugging message when you open 
a file and when you close it, to see if you didn't forget to do that. Note 
that a file is automatically closed when the File object is released.

I can't say more at the moment without more information. I'm not sure it is a 
Gambas bug.
