Overlapped timeline elements

Hello,

Working in Captivate 10, non-responsive.

When I try to reorder items on the timeline, the often overlap. The element will still be listed on the left as a separate item, but is shown atop another item. (See screenshot.)

This isn't a huge disaster, and does correct itself on save and reopen. It certainly does make working with the timeline more difficult than it should be, though!

Any suggestions or workarounds here?

Thank you!
