thanks, Markismus, tapping on the bottom right corner did the trick (still half cut-off progress bar in portrait mode though)

I'll try out fmon now (having so far only used pbchess as launcher)

edit: deleted the old koreader and fmon and vlasoft/pbchess folders, re-installed just fmon and koreader (without pbchess/coolreader) - works smoothly with built 2014.04-62, built 67 still doesn't open
