In fluidness exercise "backspacing" to much prevents you from finishing exercise

[zob]

In ubuntu 12.04, 64bit, Klavaro 1.93 from repos. Danish language exercises and keyboard layout.

Reproduce bug.
Do a fluidness exercise. Write a few correct words, now make a few errors, let's say four. Then backspace "accindentally" five times. Now you can't find back to the "right" place. Wherever and whatever you write you just get red letters (errors). Or at least so do I.

Please tell me if there is anything else I can do to help you test this application.

Sorry. Too late. I just found out that this is a duplicate of https://bugs.launchpad.net/ubuntu/+source/klavaro/+bug/596267
And seemingly cannot be fixed.
