Kneeboard controls not responding

[Gryzor]

After flying some modules (like Mig-21) when I fly other aircrafts (mostly FC3 Su-27 or F-15), key controls of kneeboard are not responding (next/previous pages and mark position to be precisse). It seems some UI conflict with those settings, anybody has this problem?

 

I have to restart sim to have properly kneeboard page everytime

I had this happen once while flying the Su-25 but don't recall what triggered it. Other key commands also failed to respond.
