IO Graph Issue or Bug

Has anyone else encountered this problem when using IO Graphs? There are times when I'm trying to change the parameters and the row will stay in "edit" mode view (see the "Time" row in image below). I can't get it to fall back to the normal display to check/uncheck the box, etc. It happens with a single row or multiple rows. If I add or remove rows, this row will stay in front of whatever is behind it. Resizing also doesn't help. So far, it seems to be sporadic. The only way to fix it is to close the IO graph and start over.
