Dailog Bozes is ZQuest windows mode don't appear.

When playing ZQuest on either X2 windowed size or X3 windows size, the dailog boxes that come up when loading, saving, etc. don't full appear. In X2 mode you can only see two lines of text at once, and in X3 it is completely missing. This makes it difficult to know whats wrong when compiling Zscript.
