Assembly Visualization, slow when connected to PDM

Hi,

I'm noticing that activating the Assembly Visualization feature (Evaluate) takes an extremely long time to complete.  For a small assembly it is taking approx. 2.5 minutes!  I don't remember this feature ever taking so long to run.

After some research I've discovered that if I disconnect from our VPN (and thus PDM) or I de-activate the Solidworks PDM Add-in then the command finishes in 1 second or less.  This points to the command looking out to PDM for information and it getting a response VERY slowly but if PDM isn't available it skips that step and processes the Assembly Vis. instantly.  

I am running SW 2024 SP5.0 with PDM.

Has anyone else noticed this slow behaviour?
