Trying to add a sound via any entity/object. e.g. any model entity/zone markers results in failure and crash : Memory Fragmentation error, then resuming from previous session which attempts to load the last saved/opened and not necessarily the one your are currently using. This results in a complete lock up of GG when it eventually resumes to the previous level and Task manager is required to force close GG. No sounds can thus be added/changed to any entity via their properties dialogue boxes. Attempting to do so could potentially threaten the credibility and loss of your levels so is best avoided as its not something one can get to work. It just wont no matter how many times you try and GG will constantly crash and become more and more unstable the more you try it.....
Happens with any entity, zone, sound consistently and always.
See attached screen shots : Try adding a sound zone to new flat level - fails - then loads last credible level - then GG freezes up and force close is needed.
