Can't see Playhead in MPEG Streamclip

Hello,

I'm having trouble getting the playhead (I think that's what it is called) to work in MPEG Streamclip. There is a black bar where it should be.

The bar that helps you 'play' and pause videos to select in and out.

I have attached a photo as example.

The only way I have been able to select IN and OUT is using the lower buttons/use the keyboard.

I would appreciate some help.

Thankyou
