Sorry to bother you with this, but I have recently noticed that there is an occurrence where, after ALT+TABbing out of a game and back into it, ACTION will proceed to take 'blank' screenshots - the output is just a black screen (no screenshot works after that).
I would not bring it up, as I am so pleased with ACTION otherwise (great performance, good quality, ease of use - keep up the great work!) except that it has now occurred in multiple games... I am not sure what instigates it, but it seems to be after ALT+TABbing out of a game and going back into it, which is why I state that (for now - only did superficial Troubleshooting at this time (Driver Updates, Restart Game, Restart System, etc)). Information from Sticky follows:
OS: Windows 10 64-bit
Video Card: NVIDIA GTX 1060 3GB
Memory: 16 GB Kingston Hyper X
Monitor Resolution: 1920x1080
Game Problem: multiple, output = black/blank screenshots after ALT+TAB
I don't mind no reply, mostly am submitting to Mirillis for possible investigation
