Hopefully it must be a bug in QTP, Hold the ctrl and try to select any tab combination with the QPT API (like expert/keyword, datasheets) it tries to select multiple option which is not an usual thing in any tab objects.(i.e tab controls/objects don't influence multiple selection)
"Whether MI had intentionally made such a feature or its a bug"
when I used the Type micCtrlDwn statement to perform multiple items selection , if the QTP failed (stopped) before reaching the statement micCtrlUp ...then my computer will keep acting like am holding the Ctrl key , and I won't be able to shift from the word view to the expert view and vice versa !!
so I have to restart my computer to flush the memory and overcome this problem, do any one have a better solution?
