Apps in Panel That Shows Windows That Disappear After Clicking on Them

I have an app that shows up in the upper right hand part of the panel. When I click on this icon, a login windows shows for the application for about 1/2 of a second, then disappears. I can’t get the window to stay open. Do you have any suggestions?

Do you know what app the icon is for? And does it say anything when you hover over it? More information would be helpful as I haven’t experienced that myself.

It’s an application for a program linking with a remote data system. When I hover over it, there’s an option for login, opening a local folder with data, and exit. I would prefer not to describe the exact app as it does reveal information about my behavior.
