Registration Panel overlaying right column

When a client goes to the checkout without being logged in, he is presented a screen from where he can choose to registrate or to sign in. This screen does not fit into a three-column Joomla page, as it spans the center column AND part of the right comlumn. What can I do to make this fit?

I have included a screenshot to depict the problem:

hmmm... I followed the referenced instruction and removed the "float: left" of ".hikashop_checkout_login_right_part" in the front-end CSS (selection is on custom). This did a very slight change, i.e. the right box top corner is now slightly higher thatn the left box top. Otherwise no change, even after clearing the cache. Is there another place to make a change?

This is what it looks like now:

Hi,

Can you try to add the "display: block;" property on the divs ?

where would I do that? Also as property under .hikashop_checkout_login_right_part ? If yes, it di not change anything...?

got it... your user documentation is wrong... instead of removing the float:left from .hikashop_checkout_login_right_part, it must be removed from .hikashop_checkout_login_left_part

you have a job opening for a tester I can apply ?

Joke aside... as you see on the screenshot: on the smaller log-in panel, there is a list of two options, asking for forgot PW or forgot UserID. Somehow my style sheet tries to place a fat square bullet in front of both list entries, and starts with the text right next to the log-in button... it looks just awful. Can you point me to the place, where I can remove the bullets and move the text below the button?

Thanks a lot!
