Michael Norman has found out that NTVDM can crash on some dual core processors. This is apparently what the problem is with the old Tame on the new Lenovo. There is a utility (IMAGECFG.EXE) that is supposed to set the "affinity" of NTVDM, but it generates an error message on my system:IMAGECFG: unable to map and load c:\windows\system32\ntvdm.exeGoogling that error message didn't turn up any help. Does anyone here know anything about this?TIA, Harry Harry Binswanger hb@xxxxxxxx
