Can't uncheck printer flags
When seeing a printer info there are some port flags (Serial, Parallel, USB).
Checking any of them and then validating makes the change. But unchecking a checked flag and validating doesn't work.
It seems it's OK, but if you leave that printer info and enter again to see the info, the flags that were checked and you have unchecked are still checked.
Sorry for my English, I hope you can understand it. :-)
