Hello @Walter De Backer,

Thank you for reaching out to us through our Community Forums!

For the sake of initial troubleshooting of this _ issue, we recommend that you repair your Nitro Pro. Please reboot your computer before and after running this repair to ensure that there are no ties to Nitro still active in the background. You may refer to this article: https://kb.gonitro.com/knowledgebase#/search/repair/000004603 

If Modify button is greyed-out, please refer to this screen-cast that will teach you on how to go to Control Panel > All Control Panel Items > Programs and Features and repair your Nitro Pro program or any application installed on your system:

If repairing didn't help, is Nitro sitting in the Task Bar? If yes, this is a common scenario when multiple monitors are being used. When Nitro Pro is opened on a monitor that is later disconnected, it won't default to a current "active" display which causes Nitro Pro to display on the missing monitor. Kindly try these steps:

1. Try rebooting your machine.
2. If not fixed after rebooting, focus on Nitro Pro by clicking on it on the Taskbar. 
3. Press the Windows key + Left/Right arrow until Nitro Pro appears.

Thank you for choosing Nitro and I hope this helps.
