Thanks Maxence, our app is “BeyondView Clny PPOB”.  We’ve also noticed that the mouse can get out of sync at times, and that it is sometimes difficult to access the toolbar–maybe your new update addresses some of this.  On our end, the app responds to the Esc keyboard event, which may interfere with the toolbar toggle also using Esc, we’ll try changing this to avoid a conflict.  We’re also trying to make our app with more keyboard controls and less dependent on the mouse.
