Sorry if this same issue has been brought up before, but I have looked everywhere to no avail. We have a few drawings here that will crash AutoCAD 2002 when we go into the Layer Properties Window, and right click on any of the layers (the right click itself seems to be the cause). Sometimes it crashes straight to the desktop, and sometimes it leaves a fatal error message, and others still it leaves an illegal operation message. We have tried to recover, purge and audit the files, and everything looks fine. Every one of our computers has this same problem with these same files, with sometimes different messages, but with AutoCAD always crashing (sometimes windows getting stuck as well). We are all running Windows 98 SE with all the patches for our hardware and software (even AutoCAD 2002 with the latest SP). It is not a hardware problem because it happens on several different computers, (from a P3 700Mhz, to a P4 1.8Ghz), all running Windows 98SE. Also I thought it might be a conflict with Norton, so I uninstalled that and installed AVG Anti-Virus (cannot run with NO anti-virus software) and still crashes. I am at my wits end to solve this problem, and the only work-around, rather than a select all layers option, we have to go through and select layers by hand...this is unacceptable. Any help from you guys out there would be greatly appreciated. Thanks in advance.
