Check box and text area erratic functionality

Hi!

After inserting a check box and text components, I get the following problems:

1) When I click on the check box, the text component appears for a fraction of a second and remains hidden. After I un check the check box and click on it again, now the text area appeares. It happens with all the check boxes I have, in other words, I need to click, uncheck and click again on the check box to be able to read the text. Any suggestion?

2) Once I have the text box open, if I click on the scroll bar's arrow to move the scroll up or down, the text component disappears!

Thank you for your help!
