Cursor issues

Hi

Everyone I want to check if anyone has the similar problem. The following is my system configuration
1. NVidia: GTX960
2. Screen size: 15
3. Resolution: 1920 x 1080
4. FlexSim version 7.5.4 (or 7.7)

Problem:
I was doing a presentation with my laptopn under a lower resolution that was set by the projector. When my cursor hover over the spatial properties (on the up and down scroll button), the cursor refused to return from "I" mode to the arrow mode. And hence the movement of the cursor anywhere will then change the value in the spatial input and change the size of the object.

It seems to be ok when I am not projector mode.

Please advise
