Thanks for valuable info everyone!
I've just installed E-sword 10.1.0 on Ubuntu 12.04 and imported my notes etc and it works like charm except for one thing: I have used the yellow marker a lot in the previous installation (ubuntu 10.10 and an earlier e-sword). But now the yellow marker does not show in e-sword. Did even reinstall from scratch and marked some text, but still no success. Any idea? Underlining works though...
Thanks again
