scfg cursor left/right leaves artifacts

This is one of those random type of things. If I'm in scfg and go to a subboard and start to cursor left and right, sometimes I'll get artifacts of the previous entry in the short name.

You can see that FSX_STA has " _ECHO" artifact from FSX_TEST_ECHO.

and now ECHO is missing...

This is using an ssh tunneled X session on Windows.
