Draftsight freezes using MOVE tool

Hi I am new to the community. I have started using Draftsight Beta 2020. I have an issue where the program freezes when I use the move tool. Not all the time but often when I select multiple objects. I thought it may be a processing issue? I am using it on a Mac mini 2012 2.5Ghz Dual core i5 running OS 10.15. 16gb ram. Is there another solution I can investigate
