Cubase freezing

Cubase
1

For some reason my Cubase cue line keeps freezing and I cannot get it to move again. However dragging to a certain point in the project still makes it pick up and play from that point. I have tried restarting cubase, but it seems to happen again and again.

I am on PC with quad processor so this shouldn’t be an issue for the computer.

Also, my automation points wont freely move to where I want them to eg. change the volume at a certain point. I can lay a point, but then cannot drag and adjust it. Do I need to turn something on for this, or may I have accidentally turned something off?

Any ideas please people?

Update,

This only seems to be happening when I try to change Automation on a prologue white noise sample. I have tried to remove it and made a new channel and made the white noise again, bit still happens.

Have also checked CPU processor useage and it is very low so should not cause this problem.

Help!!
