You might try resetting Poser back to the "Factory" State.

Here's how to do it.

[menu] "Edit" >>> "General Preferences..." >>> "Document" >>> "Launch to factory state"
... also ...
[menu] "Edit" >>> "General Preferences..." >>> "Interface" >>> "Launch to factory state"

If this does not work, try increasing your screen size and then restarting Poser.

Remember ... "With Poser, all things are possible, and poseable!"
