When SW crashes and i have a part/assembly open it leaves the ~$ file in the part folder. When I open that part back up it says the part is "Read Only" and I can't edit it. This requires me to close out, delete the ~$ file, then open the part back up. Sometimes the ~$ doesn't let that part show up on a drawing or in the BOM for the assembly.

Is there any way to prevent this from happening?

Has anyone else experienced this?

Windows 7 32bit
