Hi,
>> Here is a prt scr of the object I referred to.
Thank your for your screenshot, however in the dwg-file you uploaded I can't find an object (I guess it's a line) at the position you showed (I have not changed the layer frozen states, let me know if I should do that).
>> About the proxy objects. I am not sure what that is
These are objects of applications, not from AutoCAD. To control and modify such objects you need to have the application installed, at least an ObjectEnabler to get them correct displayed and plotable (but this depends on the application itself if ObjectEnabler is really needed for selection/plot/erase/...)
In this drawing I see object from application "ImpactRcBase" as well as objects from Civil 3D.
>> It seem to be connected to the application "Impact" which I have installed and
>> has been working fine in other files.
OK, when you open this dwg-file with AutoCAD and a profile where this application is not activated, do you see the same effect(s)?
>> None of my colleagues have this problem with the wrong selection preview.
Do they have the application installed or plane AutoCAD/AutoCAD Architecture?
>> We have the some updates and versions of programs on our computers
Make sure that your versions and updates matches with the workstations where you don't see this issue.
Also try to turn off hardware acceleration (command _GRAPHICSCONFIG) to see if it shows this behaviour then too.
