The same goes for the "Stop and Resume if no data received for [ X ] minutes" box.
The 2 boxes underneath these 2 never disable themselves when unchecked so the enabling/disabling sequence of their editboxes isn't necessarily as broken as the 2 above, however they should also be disabling the editbox portion of the line when unchecking them as well.
Perhaps this is in other portions of the preferences screen with other boxes as well, I don't feel like running through them all.
1.4.800 btw.
