Cursor limited to the top quarter of the game screen.

Hi.

I am following the tutorial I found on youtube to start out, and when I run the game the mouse cursor is stuck in the top left hand quarter of the screen. I am using a mac.

Is this a bug or a setting that I can change?

Thanks

I justy thought I would add  more details. I just transferred the file over to my Windows laptop to test, and it works fine on it. It seems to be a problem specifically with the trial version of Mac VS5.

Is this resolved in thecurrent version of VS5 for Mac? It's a major selling point for me.

Thanks in advance.

I am running a 2017 iMac with macOS Sierra 10.12.6.

The area the cursor is restricted to seems to be exactly 1/4 of the actual screen dimensions.

Thanks.
