Cue Update Problem

I'm having a bit of a problem with the updating a live cue. For example in a cue list of around 50 cues I'm opening one of the cues in the middle (For example: 3.50) and when I update a fixture on 3.50 and press open cue the user interface on the Hog PC (Nano) vanishes but the lighting board is still responsive. It happens around 1 in 5 times and I've been able to replicate it even after a complete system reformat and reinstall of the HogPC. Running the latest version of the software.

Also another issue when updating cues is that updating for example cue 3.5 will cause the next few cues down the list to also update that particular fixture even though only cue 3.5 is open. It's as if the cues below the one being edited are inheriting the fixture update when it shouldn't. Is there a way to fix this (not sure if its a setting issue possibly from my end). :confused:
