Quickinfo not shown for toolbar button: In one of my toolbar pushbuttons I have defined a quickinfo, but it does not show up. The quickinfo of my next toolbar button is shown. When I switch the two button definitions in my script the quickinfo of the other button (now the first one) is not shown. What could be the reason?
The reason is that GuiXT assigns a funcion key to each of your pushbuttons, e.g. F5 for the first one and F6 for the second one. To do so, a free function key is searched, i.e. one that is not active for an exsiting SAP function. If GuiXT assigns a function key that SAP GUI has reserved for a menu function that is inactive (grey), SAP GUI does not display the quickinfo.

In your toolbar definition, assign a different function key to each of your buttons.
