I am having a problem moving items around within an already created schedule. When working on a schedule late last week after having the software open for about 90 minutes I was unable to move items up or down in the schedule (I tried drag and drop, the move item from the gear menu and the move item from the pop out menu). I just tried again today and it seems to be working fine but I've only had EW6 open for about 10 or 15 minutes. Is there a problem? Am I doing something wrong?

This not a known issue as far as I know, but it could be possible that EasyWorship may be running out of resources for some reason.
If it happens again, open task manager and click on the processes tab. Check out much memory and cpu EasyWorship is using.
