For quite a while now, whenever I opened a PDF document the kpdf window appeared only a few inches tall, not max height. I have tried using

=> Window Settings => ____________________________________________________

Yes, I've noticed kdf acting strangely. However, I close it, reopen and all is well. Here's a screenshot of what I get.

Ok never mind, I can't get it do it now.
