Are you moving the clips with the mouse or keyboard shortcut?
What exactly happens when you try dragging an effect to a clip?
Photoshop has a separate forum.
I move with the mouse.
I rebooted... and it worked for another 10 minutes... and then failed when I highlighted 1 picture/sound clip and tried to move it 'up' one track. Double checking Photoshop... before I rebooted.... confirms that I can't create a 'new' canvas. I get the NEW properties box... and when I say yes... the box goes away... .and nothing is created.
I rebooted... I moved the clip successfully ... then went immediately to Photoshop and had the same problem trying to open a file or building a NEW canvas. Rebooting again now... hope to hear from you shortly!

Be specific about what happens when you try moving and it doesn't work. Also the effects.
I think I'm having the same problem, too, although it only happens on some clips.
Specifically, I'm having a problem with a dynamic-linked AE comp.
I am replacing a title that I have on the timeline with this comp (the title was a placeholder), so I drag it into V4, while the placeholder is in V3. Then, I go ahead and match up the opacity keyframes, and delete the placeholder title on V3.
I wanted to move the comp from V4 to V3, but it's stuck. Literally will not move. I try dragging it anywhere, and it won't drag. It can be deleted. Opacity can be manipulated. It just won't physically move when I click and drag.
This only happens sometimes, but it's not the first time I've noticed it.
I've just had this, clicking on the track selection (V1, V2 etc.) to select the track cured it.
Thank you! The next time it happens I'll try that out.
