Cursor not visible after changing monitor!

It was working on my 17 inch lcd, but when I changed to a 22 inch lcd, the cursor simply was gone!

I have to press ctrl+shift+c to get the standard windows one, but when I shift back, the cursor disappears.

I am using the free version of CFX - I have purchaed it, but I use it on my home computer too, and I can't seem to install it on another computer.

(if anyone can confirm this, please acknowledge it. Do I have to buy a new code for every installation?)

BTW, my work computer runs Win7 - no problems with the older screen, no cursor on the 22 inch.

Can anyone help? Thanks.
