Topic Title

Sometime I notice that my undo icon is not longer working It seems that in working with a large drawing that the cache is full. This has not happened in previous versions. Is there a setting that needs to be modified? or is this something else?

Thanks

If you do a Save As or if you purge your symbols are a few times I know the undo buffer gets wiped out. There might be one or two more things that do it but I can't recall right now what they might be.
