This is the same setup as me and I've not experienced any crashes yet. I often have two or three instances of the IDE open at the same time and even that hasn't upset it.
Is there anything that you might think could be the trigger for it happening? Eg does it crash just as you try to compile or is it only when trying to open or using the designer? Maybe it occurs when trying to load a module or do a search?
The more information you can provide
@Erel the better his chance of fixing it for you/us.
