Error While Labeling w/ DLC2.2b8

Hi DLC Community,

I have been working on labeling frames for a new network and I have about 1000 frames and it has happened about three times now where I am switching between frames and adjusting labels or continuing labeling that the GUI freezes and does not respond back… I thought it was something I did, but now I am thinking it is a bug… Nonetheless, I just wanted to share this issue and get some feedback on what the possible issue is that causes it!

Thanks in advance for the help!
