Mouse move issue during ClickImage activity use



I use a UIPath.Core.Activities.ClickImage because I’m using Citrix application (so only image recognition can be used), but when I run the process on FOR, I can not use the mouse as the robot is then lost.
I read in the UIPath documentation that this issue can be avoided by using SendWindowMessages option set to true (false is the default value).
My concern is with this option to false, the process work well until I move the mouse during the excution, whereas when I set it to true, the robot can not click on the image and the process is blocket.
May I lost something ?
This option doesn’t work with Citrix environment ?
Do you know another way to avoid mouse movement issue in my case ?

Thanks for your help.
