I was reading Habakkuk today and as I was scrolling down to chapter 3, Logos 4 became real slow. Then Text Comparison started to flash on and off - that is, the texts appear and disappear. Then, it alternated between display of abbreviations of the bibles (NTL, ESV, NAS) and the full name of the bibles (New Living Translation, English Standard Version, New American Standard Bible: 1995 Update). The actual bibles were NLT, ESV, NIV, NET, NAS.
Meanwhile, Logos 4 was sluggish and would not close. I had to end the process Logos4.exe*32 in order to close out the program, as nothing else worked. I had no other applications running. I checked memory usage and it was not an issue.
Below is a screenshot of my workspace prior to the strange behavior in Logos 4:

I also have attached my crash log.

Update: This occurs when Logos 4 window is at maximum. When I minimize the window, Text Comparison behaves.
Update2: Below is a screenshot of Text Comparison buggy behavior:
