A Problem

Hello everyone,

    I have got a problem recently, I am using Adobe Acrobat to study, I mainly use the "Highlight selected text" tool to highlight my pdf; since I am studying by solving questions' banks. The problem is that, whenever I use this tool to highlight a text, it switches immediately to the "Select text" tool.

    I didn't get this problem at first, the app was working perfectly before. It don't switch randomly when I am using other tools, only the one I mentioned.

Thank you for your reading.
