Hello, I am developing an Internet Explorer toolbar that also contains a combo box. The problem is that pressing backspace in the edit field of the combo box has the effect of pressing the Internet Explorer "Back" button. So IE browses to the previous page every time I press the backspace in my edit control. My toolbar plugin is modeled after the kbbar example provided by Microsoft. The TranslateAcceleratorIO, HasFocusIO and UIActivateIO methods are implemented. Can anyone hint me towards a solution of this problem? I would greatly appreciate your help on this. Francis
