Missing part of New Product page in Admin

[xelax]

Hello!

 

I'm setting up a new install of V2.3.1

 

Have set up my first product category but when i try to add a product I only get the top half of the New Product page.

I scroll down and the page stops at 'Product Image'.

I have attached a screenshot (below) so you can see what I mean - note the scroll bar on the right is all the way down!

 

You can also see there is no html editor in the product description box (there is one shown in the documentation that comes with osc).

 

I'm sure I'm just being dumb, but any help much appreciated!

 

Thanks!
