CommandBars & DockingPane Not responding to clicks

This is an old case, but we started to get too many reports about it... In many cases, the CommandBars and DockingPane components do not respond to our mouse clicks directly, which means, when you press on a toolbar button for example, you see the button pressed but it feels like you didn't release the click (like if you press the left click and hold it), and you will need to click again in order to fire the event and press the key..

Same for the Docking component, when you try to resize the forms for example from the splitter, we release the mouse, but still, the dock will be moved with the mouse (even after the release, like if we didn't release at all), which will require to click the mouse again to release this splitter.

This is something annoying the users, and we got many complaints from our clients about these issues.

Is there any solution for this in later releases after (15.3.1)? I tried the (16.3.0) but it was completely not stable from our side to use it, since the drop down control was keep hiding automatically when you press on it, so we turned back to 15.3.1.

Did anyone face such issue and found a solution?

Thanks.
