    My users are running into a problem with the SelectionMiniToolBar, where it either doesn't show at all, shows slightly transparent, or does one then then other.

    After digging into it, it seems to only happen when the user selects text, but stops selecting somewhere near the top of the control, where the toolbar would become visible above, or to the side, of the rich text box.  This can come from selecting text towards the center of the control and selecting towards the top, then releasing the mouse button.  Often when selected this way, the toolbar will display mostly transparent, or just never show up.

    A little about our implementation of the RadRichTextBox.  It's in its own user control, where the boundary of the user control is no bigger than the RadRichTextBox.  Each of those user controls is part of a list box item inside a RadListBox.  I don't know if that makes any difference, but I was wondering if it's an issue of the toolbar appearing off the control; since selecting text further down in the document so the toolbox appears mostly inside the RadRichTextBox control, allows the toolbar to function as expected.

    I can reproduce it with our application running Q3 2014.

    What can I do to resolve this behavior?

    Hello Nathan,

    I've tested the showing of the SelectionMiniToolBar in RadRichTextBox inside a RadListBoxItem as you described and everything seems to work as expected. Here is a recorded video of the demo which illustrates the scenario. The SelectionMiniToolBar control gets semi-transparent if you do not hover it with the mouse pointer because that was its behavior in MS Word 2010. In MS Word 2013 that behavior is different.

    If this is not the case, please try to record a video in which you are showing the issue, or to send us a sample project where the problem can be reproduced.
