Just a guess, but is it possible that there is an INKEY statement somewhere in the form or startup proc? By default, INKEY does not recognize a mouse click unless you specify M as the second parameter.

>I have encountered a strange problem when opening a form automatically as part of the startup sequence of an application I develop. The problem only occurs in Win XP. After the form has been opened, the mouse cannot click any command buttons on that form. (The command buttons are accessible via the keyboard though.) I have to open another form first before the mouse is working normally in the first form. What can be the problem here?
