Severe screen flickering launching show

Hi,

When I launch my show on the H4 for the first time after booting the console I am seeing a severe flicker on all 3 displays for about 5 seconds. If I log off and back on it doesn't happen.

v1.2.0 connected to Capture Polar running on Windows 7 PC.

It only occurs on the one show file and it happens whether physically connected to the network or not.

Should I be concerned about the state of this show file? It was created on v1.2.0.

Cheers

Colin
