I already tried the alt thing to do it, however it hasn't worked. That's why I made a thread here.Hold the ALT key while dragging each side to the size you want...
Again I already tried this method but it sadly doesn't work for me.That's the only way I know how to do it.
If you see the red bounding box around the source and click on one side of the box you should be able to drag the side to the wherever you want.. Make sure the width and height of the source in the properties box is bigger then the actual source..I usually set mine to 800x600 or something similar.
Well, sorry it doesn't work for you but I'm sure there is someone here that can read your log and figure it out..
Is it a web source?
can you post the link?
