10 minute hang when "looking" for Xref

I have a drawing with a few moderate sized xrefs of building sections that if I miss a pick (not directly on an object in current drawing) will lock up for ten minutes or more (I timed it). What would cause that? I checked Task Manager/Performance tab and Acad.exe is using 100% of one processor for the whole time. Whyyy meeee. This hang up (while I write this) is going on 15 minutes. I am just trying to finish and save. (Friday night, time to go...)

PS that is just punctuation marks in the Title - I don't swear as a rule. Grumble a bit, but no swearing.

What are the specs on the computer? How much RAM? What video card is being used? Have you purged the drawing including any unreferenced regapps? What OS are you running? When did the problem first occur?

Mr. Mark,

Thank you for reading and responding to my query.

It is an average professional computer that works well 99% of the time. (There are about 30 similar or identicqal computers in the office, all with different problems ;-)

I was not looking for a chip specific reason but rather to see if someone has had a similar symptom and how they solved it.

Thanks again,

John

Maybe you have an overabundance of Xrefs.

Maybe its a network problem.

Do you really want to try and troubleshoot the problem or not?

Thank you for responding. I appreciate your help.

The abundance of Xrefs is the likely target. I found that there were Xrefs about three of four layers deep. I had tried to edit one in place and that is when the delays started.

The network was fine as I still had access and everone around me was also accessing, loading, saving to the server without problems.

Can you tell me more about the Xrefs - how they should be done to have the utility but without the problems? I suppose I'll learn eventually like I learned not to touch bare, live wires but any suggestions that would help shorten the learning curve would be appreciated.

Thank you again. John

make sure your xrefs are overlays not attachements so you dont get xrefs inside of xrefs inside of xrefs....

There is a similar problem with ACAD 2008 at my office, I've been looking into it. I read you can use the command -SCALELISTEDIT (note the hyphen) and reset all scales in the drawings, and that it would help. I am still learning about this. It has not helped me much in my case, but I haven't ran it on every xref yet either.
