Can't edit Fonts

For some reason I am unable to edit the fonts in my events.

When I try to edit font in a text the font window opens up for a split second then automatically closes itself, the ok button seems to be auto-selected or something.

Has anyone had this glitch before?

This is a known issue that has been fixed in the newest version of SuperLab. What computer operating system are you using (10.6.8, Windows 7, XP)? Also, what is the version of SuperLab you are on (4.0.7, 4.5.0)? Below is link to download the latest version of SuperLab 4.5.
