Hi,
don't know what it is but Software is running worse.
I'm working on a lightshow - Editor goto Live goto 3D View etc. like it's usual to work with.
Suddenly copy and paste via Keyboard won't work.
Close Software (SW) open again - working again.
Next problem:
Gone back to SW Version 7.1.42 and tested the following:
Opened a timeline and started it - stoped it with the space button of the keyboard - gone to buttons - (here are 3 Button controlled via Keyboard configured as FLASH) hit those buttons and it's working - shifted the 3D window - and it stoped working - gone back to the timeline - started it with space button of Keyboard - stoped it immediately - and 3DView works again with the buttons until you shift it again.
Clicking on another scene button got it also back to work.
If I shift the 3D View window during using those 3 buttons the buttons will freeze!
It seems that the problem only appears whith buttons configured as "FLASH".
Hope I've explained it comprehensible.
Everything checked with 7.1.42 and 7.1.54. Fault is reproducible.
