Problems with Calendar version 1.2.3

Hi. I just downloaded version 1.2.3 of Calendar and I’m having the following problems:

1. Previously, I was able to make my category list horizontal by editing configuration in Calendar Options. That doesn’t seem to work anymore.

2. How do I remove highlighting from events posted in my Upcoming Events list? I don’t want them highlighted.

3. There is now strange background highlighting when an event in the Upcoming Events list is hovered over.

4. Supposedly event listings can be posted onto pages using tags. How do I do this?

Thanks!
