When I opened CPT through RSS file, it's full of not responding, lags, and extremely slow. I see none of these issue when I opened the same slab from CPT. Is there a way to get away from this?
When you run Ram Concept this way (tight integration), the Ram Concept file is embedded within the RAM SS zip model and updated in the working directory. There could be some latency due to the location of the working directory, or the available space on that drive, or some virus scanner or firewall is causing interference. Regardless, pulling out the Concept file and using it stand-alone is a fine alternative (even preferable IMO).
