A very simple construct. GNT28-T, open a construct, put a Null in the first column and a verb under it in the first column. Hit enter. Acc disappears. 3 out of the last 4 times I've tried this Acc has exited.
In general I've noticed that syntax constructs will crash Acc somewhat randomly usually after a number of constructs have been run. I have not been able to pin any case down as really reproducible, except the above. I suspect there may be a resource leak or something but have yet to track it down. Has anyone else seen this ?
