Bug in proxy server setup screen

Just been trying to config up using a proxy to communicate with the outside world, and found an ickle bug.

1. Check either HTTP or SOCKS boxes (doesn't matter which one - both do the same).
2. Remove the port number value and leave blank.
3. Click ok. I see two empty BOINC GUI warning dialog boxes one after the other.
4. Uncheck the box selected and click ok. Same empty dialog boxes pop up.

I know it's not going to rock the world finding this, but I thought I'd let you know!
