[List of problems with VW 8.5.1]

I have also encountered a problem when inserting PIO windows and doors. If I change the PIO option to insert on a class other than the given (which I think is a great improvement), the object appears behind the wall. Only if I "send the wall to back" will the window/door come up. Has anyone else found this problem? Is there a fix?

[Pan and Zoom causing Shut Down]

We have occasionally encountered a problem that when panning or zoooming the machine will lock up. We must hard-boot the machine because ctrl-alt-del does not do anything. We are on Win98 using VW 8.1. Has anyone encountered this problem? Is there a solution?
