Circular Stair symbol overwhelms graphics card in General Discussion Posted August 6, 2010 I just saved a copy of the problematic drawing file (300MB), and I got an <> warning. But my memory monitor says I still have 72% (15GB) memory free. With VW running (10MB), the total memory usage is 22% Could VW be having problems accessing the memory??? If so, what can I do about it? Would it help to set the Windows 3GB switch to allocate more memory to VW? Has anyone tried this before?
