Right-Left Scroll doesn't show initially

Yes, this happens every now and then. maybe once a week. mostly after i have connected another device like a beamer the day before.

My solution is to use the windows resize button on the screen. click on it to resize smaller and next click on it again to resize in full again.
After that the scroll bars have returned.

This is something mindjet developers should look into. Not a major problem, but clumsy.

I got the same issue on Windows 7 clients. If I open a new file the horizontal scroll bar is not visible. After I click on "File" and go back to the file or click on detach the tab the scroll bar is visible.

Is there already a solution for this problem?
