I found a strange behavior exhibited when closing a floating window. If I have my main Logos window minimized and then click the red x on the floating window (so as to close the window) my main Logos window automatically reappears.
Steps to Reproduce this Issue:
1. Open Logos and Open the ESV and ESV Study Bible.*
2. Open the ESV Study Bible in a floating window. Then return to the main Logos window so that you are viewing the ESV.
3. Minimize the main Logos window.
4. Close the floating window that was behind your main Logos window. This should cause the main Logos window to reappear.
*Note: You must have at least two resources open to reproduce this bug. One resource must be open in the main window. If you have no resources open in the main window you can successfully close the floating window without the Logos main window reappearing.
