I am currently running PM 4.6.5 on a Powerbook laptop (pre-Intel). recently, the app started becoming sluggish or unresponsive when ever I try to change functions, such as after editing and I try to transmit, it takes a few seconds to react. while this is happening the CPU usage according to my Activity Monitor spikes then the app reacts. Also when I am changing code replacement or ingesting when I click to proceed there is a delay 5-15 seconds long before the app responds. Any suggestions.
