**Describe the bug**
I've been using CopyQ all day and it has just stopped copying. My last copy that has been stored in Copy! was about 3 hours ago. I have rebooted and shutdown and rebooted a few times now. I have closed CopyQ several times and reopened it. Ihave changed the number of clips (increased) and that has not helped.

The number of clips to store is set to 5000 and CopyQ shows a count of 4999. I increased the count to 5001 and CopyQ is still showing 4999.

I changed the max clip count for the main clipboard tab to 4995, closed CopyQ and restarted the program. Now the count shows 4995 but it is still not copying / not storing any clips.
