I may have found a few bugs.
I noticed today that BIT hadn't updated my weather overlay since 5:16 AM May 9th.
So I opened up the GUI and clicked the "Update Weather / Save" button.  It didn't succeed.
It said in the upper right that it would retry in "30".  That number didn't tick down or anything.
At this point I tried to close the Blue Iris Tools window using the standard close button in the upper right.  It didn't work.  I could minimize the window or click around to other tabs, but BIT wouldn't close.  I went to task manager to kill it and noticed BIT was consuming 1 entire CPU core.
Then I killed BIT via the task manager and started it again.  Weather updated immediately, just fine.
-----------------
Then I went looking to see if I could turn on logging, and discovered more problems.  I found the "BIT Logs" button in the Options tab.  Clicking it opened the log window offscreen to the left with no way of moving it on-screen short of editing the settings file.
Also, the first time I click "BIT Logs" after starting BIT, it opens the Nvidia Control Panel along with the logs window.  I can't begin to explain why, but it is fully reproducible every time I close and open BIT and click the "BIT Logs" button.  Further clicks of the BIT Logs button only open the logs window (not the Nvidia Control Panel) until I close and reopen BIT.
I was running BIT version 1.3.0.  I just now updated to 1.3.2 and can confirm this BIT Logs + Nvidia Control Panel issue is still happening with it.
