PS: More tests revealed that it is more likely for setup "c" to get stuck very early at a scan, or to produce an incomplete and garbled scan (perhaps with mostly random junk of uninitialized buffer memory). The kind of delayed but in the end successful scanning like in the earliest few tests is more an exception then the rule. In other words, my further results came closer to what you are getting. -- Stefan Richter -=====-====- -=-= -=-=- http://arcgraph.de/sr/ |
