FLP V 8.2, Release Build 2766
Windows 10 Enterprise, V 10.0.15063
The problem occurs when FLP is running, but not the active window. When I make FLP the active window, it sometimes hangs and the top bar says "Not responding".
If I kill the FLP task, I can restart FLP without problems.
I can't recall how many times this has happened, but enough to prompt me to report it, e.g., maybe 3 to 5 times in the last couple weeks.
This Windows PC has had other problems with freezing up, though not recently (e.g., more than 3 weeks ago). So, the problem may not be with FLP. If others are not reporting this problem, I suggest ignoring this message.
