Whenever I open a drawing file (SW 2010 SP4), I see it re-rendering everything. Sometimes things show up where I saved them, sometimes not. It's like playing russian roulette with your drawings: everytime you open it, it could explode.

I have a great idea! How about drawing files have tables of locations for each object that it can refer to. This would be superior to the current method of tatooing locations on the back of angry ferrets in that the chances of catching rabies would be significantly lower. Please review my suggestion and let me know how it's received.
