Bug with Windows 7 and AutoCAD 2012 LT

[Dag]

Dear experts,

first of all let me say that I am from Germany and my english is not so good, so if someone find a spelling misstake, feel free to keep it .
All expresions in this text has been translated because I am using the German version of AutoCAD so they might be diffrent from those you know.

I have been looking for a solution in German Forums but we couldn´t figure out a solution yet. Therefore I have to rely on your help.

The Problem:
When I try to save under or open file AutoCAD collaps. (The window is getting "untouchable" and at the top is written: "(no reply)"
in german: "(keine rückmeldung)"
I assume everyone who use Win 7/ Vista knows what I mean

When I deinstall then Install the programm new It works for a cupple of hours, than the same problem appears. (I choose the folder to save in: P:/... witch is the server. This might be a hint for someone?)

System:
-Windows 7 Proffesional 64bit
-pentium dual core E5800
-AutoCAD LT 2012

Installation was made as admin!

The problem was there before and after installing windowns update.

Thank you for your help!

Best regards from germany!

Guten Tag Mein Herr. OK, that's all the German I remember except a poem about cows and how to count.

AutoCAD LT works for a couple of hours but when you try to save it crashes. Is that correct?

You are saving to a server but not to your hard drive? Have you tried saving to the hard drive?

Hallo mein Herr

well for the first cupple of hours AutoCAD works perfekt. In this time I can also Save as and open file. no problem. Then after a while i dosent work any more.

Was I probably was not clear about is. I can save! it is just the button "save as" and open which dosen´t work right. so If I open a file through folder in windows (not in CAD). I can save the file. (even if it is on the server)

Well do try saving at local I would have to open the "save as" window. but this does not open.

Sounds like there is a dead shortcut in your "open" and "Saveas" window and Windows is hanging up looking for this non-existent item (drive letter, network shortcut, etc).

Try disconnecting the network cable (and any other network connections like WiFi) and try again.

done. no difference. still collapse

What exactly is not working? Do you gewt anything on the command line?

[Dag]

There are quite a few "Saveas causes crash" threads at the Autodesk forums, most seem to be unresolved, but here's one possible cause.

I just try a new video Card with newest nvidia driver. Did not help.
although I got a new Card sponsored by boss

The Card I have is not in the list of "certified cards" on the AutoCAD site. How cerious do I have to take that certifikation?
