help files

hiya,
just stumbled across a problem interfacing a .htm helpfile with vb. The helpfile is id'd to the controls in vb fine. It has to be opened off a custom button. Dbl click gives help index page, single click gives mouse pointer+question to allow context sensitive help. Basic problem is with combo boxes. Clicking on them doesn't fire their click event, only changing their values seems to with style=0 (dropdowm), so my little sendkeys("{F1}") doesn't happen on these controls. Anyone know of a work around for this ?


thanx a milion
