Freezing and Lag working with Read-only files from PDM

Hi everyone

Having a problem recently with Read-only parts within PDM. Note that this part is checked out, it simply has the Read-only attribute checked in the properties. I've noticed that when working with Read-only parts from PDM, either editing them directly, or an assembly that contains them, Solidworks sometimes freezes up consistently. It appears to freeze on most operations, including saving and tabbing between open files. When this tag is removed from every part in the assembly, the problem seems to go away. Does anybody else have experience dealing with something like this? Is there a workaround or some way of easily mass removing this tag from parts? Thanks
