I'm having a really strange problem with my software I never had before. Maybe it's because I updated to R15 a few days ago, but i am pretty sure that it didn't happen the first days.
So, the problem is that when I'm moving an object or a camera that has a keyframe on it's position property earlier in the timeline and I move it around, the object suddenly jumps back to the position of the previous keyframe after moving the camera. Maybe it's hard to explain, so I'll post you a quick video.
As you can see in the video I'm not scrubbing the timeline, so this jump should not happen.
I'm really looking forward to hear from you guys, and hope to get an answer and help people that maybe have the same issue.
Seems like something is causing a refresh, which shouldn't happen from regular viewport manipulation. You're not hitting the "A" key? Do you have any plugins? If so you might try removing them. If the problem clears try loading them back one at a time until you figure out which is causing the problem.
