Hi list, I experienced exactly the same problem with Solidworks 2007 http://appdb.winehq.org/appview.php?iVersionId=8983 with occasionnal big slowdowns caused by a 10000x10000x24bpp bitmap allocation. In this case it doesn't crashed, but allocate more than 1GB of swap. I filed a bug : http://bugs.winehq.org/show_bug.cgi?id=9561
