[feladat @ 124] Minor bugfix. If number of zones exceeded maximum row amount and the '0-9' was selected to be shown, the '0-9' was not rendered in bold, where in all other cases the selected letter is shown in bold.

[feladat @ 123] Reverting to changeset:121. Problems that were fixed in changeset:122 were local problems only.

[feladat @ 122] Fixing a number of 'division by zero' errors introduced changeset:121. Changed from constant to a normal variable. May need to be reviewed in a future cleanup.
