Thanks David, that was it; with the nodefault in the text/edit boxes, the form responds as expected.

>>Thanks for the reply. The form is based on a subclass that makes it modal and has some cosmetic preferences set + a timer which will close it after a timed lack of keyboard/mouse activity. As far as I can see, there is nothing trapping the keypress events other than command button hot keys (there are 26 of them!). Funny thing is that it does trap the tab and backspace keys. For the rest I get 'The control is read only', which refers to one of the disabled text/edit boxes. The 'on key label' bit works, though I consider that a kludge. With regards to the environment, I'm not sure how/why it would affect the handling of keystrokes.
