Service Manager Keys do mad things

[Tim Bentley]

I'm running 1.9.7 on Kubuntu 11.10 and I can also verify problems with the selection of the current service item when using the arrow keys for navigation.
If I press the right arrow three times in quick succession the output jumps three service items down the list and then jumps back up one item, but leaves the selection in the service manager three items down. Thus the live output, slide contents and preview all show the contents of two service items down the list while the service manager has the third service item selected.
If I do the same thing with the left arrow, a similar thing happens but in the opposite direction.
If I press the left/right arrow key four times in quick succession, then the output jumps to the correct slide and then back two slides.
If I press the left/right arrow key five times in quick succession, then the output jumps to the correct slide and then back three slides.
Sometimes, though I am also seeing another problem. Sometimes (although not all the time), if I hold down the left/right arrow key slightly longer than necessary to jump one slide, I end up with a situation where the service manager selection moves two service items, and the Live slide text shows the correct text, and the live output shows the theme from that selected item, but the text from the in-between service item.
Sorry if I haven't explained myself very clearly! It is a bit hard to explain sometimes!
