Freeze when rearranging panadapters

Found an issue that is pretty easy to reproduce and causes SmartSDR to lock up completely, where Windows throws up the "SmartSDR is not responding  - close/wait" message.  Here are the steps I've been taking to reproduce:

1) Open 6 panadapters (4 didn't seem to trigger it, or at least not as quickly - I didn't try too hard with 4)
2) Maximize one of them.
3) Un-maximize that same one.
4) Drag and rearrange that, or any other, panadapter to reposition it.
5) Repeat steps 2-4 a few times (might take 4 or 5 tries) to trigger the app hang.

After the app hangs, if click on it with the mouse, thats when Windows pops up the "not responding" window, and if I let it stay there for another few seconds, a ~2 inch wide blank vertical bar shows up on the right edge of the screen (from top to bottom, on top of whatever is on the screen).  It's not the windows 8 "start" bar, that bar still functions properly.  After I kill the SmartSDR app, that blank bar goes away.

In addition (no idea if this is useful at all), if I have Perforator attached to the SmartSDR process, at the time of the app hang, The "HW IRTs per frame" drops to zero, and the other metrics freeze at what I assume was the last known value, such as:

Frame Rate: 28 fps
Dirty Rect Addition Rate: 344 rects/s
Video mem usage: 45.02mb (out of 2gb)

My OS is Windows 8.1, current patches.
SmartSDR v1.1.3
FlexRadio 6700

Let me know if you have any questions.
