Hello. I saw your reply to my review of Coollector Lite and I think this is how I should reply. In answer to your question, yes, I will try to help you fix this bug.
Steps to repro:
Click on single-pane mode. Dismiss the pop-up explaining single-pane mode.
Click on Barcode Search. Enter a barcode. Click on Search
Click on one of the Icons for the titles returned.
The error box is stuck under the movie title box that appears.

The only thing I can do is move the movie title box out of the way, hit continue to dismiss the error pop-ups and then the app crashes. I then get the option to report to Apple which I did several times.

I am using a iMac 27", Late 2013, Mojave OS 10.14.5. I do not have a 2nd monitor. I do not see this problem if I stay in multi-pane view.
