Hi, Every time I try to bring up a plot with individual distributions of WRES, Census crashes. It's something like a hit-and-run raid. The program is closed down immediately leaving neither error messages nor prisoners behind. Has it something to do with my maybe not always so well-behaved data or is it something else? /Jacob ------------------------------------------------- Jacob Brogren MSc Pharm Senior Research Scientist Pharmacometrics Clinical Pharmacology and DMPK AstraZeneca R&D Södertälje SE-151 85 Södertälje Sweden Tel. +46 8 553 236 33 Fax +46 8 553 274 91 jacob.brogren@xxxxxxxxxxxxxxx www.astrazeneca.com
