A reinstall of Windows is pretty well out of the question right now.
So, it wasn't there before, switched harddrives, it's there. Then switched back to original turntable harddrive, still there.
Is there something network-wise that sticks out that could cause this problem?
We've disabled virus protection, it didn't fix it.
My autocad did the same thing. I had to disable my 'sync settings with the cloud' setting and uncheck all the autodesk 360 options in the tools. After that I did not have the problem again. I tried it again today to see if the new service pack fixed any of the errors I use to get and it did not. I still get all the sync errors and the freezing. Might be worth a shot to try.
No, we checked and our autosave is setup for every 10 minutes, while the freezes happen every 30 to 45 seconds. They last around 5 to 10 seconds.
I'm experiencing some freezing of AutoCAD 2013 as well. Luckily it occures only once in 20 minutes. I'm running a fresh installation of Windows 7 64-bit and on a SSD. Freezing usually appeares when I'm starting some command (like edit Mtext or drag line point).
Start a new file. Not from a template.
Draw a few items.
Draw a few more items.
SAve it again.
Repeat the process, but from a standard template you all use.
Repeat the process using a current "problem" file as the template.
Which one is the problem trigger? Or is it all three?
Have you checked your AutoSave interval?
Our fix, so far, was a combination of things done on the network and servers since it started around Patch Tuesday. Exactly what was done, we don't know.
