MCP keeps resizing window

I did a forum search before asking and found nothing...

If I start a new video file in Media Player Classic, it resizes the video window. I resize it back to where I want it, and when the next video starts, the window resizes up to huge again, and I have to re-resize it back to where I had it. How to I tell MPC to keep its size and stop changing. I have "Remember last window size" ticked, but it doesn't seem to help. It never use to keep resizing at the start of Every new file. How do I fix this?

*Edit*
Nevermind, Stupidity struck. In the options, under the Playback tab there is "Auto-zoom". If this is active/ticked, it causes the window to resize on every new playable.

Correct, "Auto-zoom" overrides the "remember window size" option. Not very logical, so hopefully they will change that in the future.
