There is something strange in the form.lockscreen. I have a form and two commandbuttons calling two child forms. First commandbutton has a "thisform.lockscreen=.T." before calling a child form and after the related "thisform.lockscreen=.F." Second commandbutton calls directly the second child form. Well, if I open and close the second child form, this disappears with an annoying refresh; it seems a very long refresh. If I open and close the first child form (with the lockscreen) it disappears faster, but not so fast as the messagebox window. This happens every time I open and close that child window. Now, if I open and close again the second child form, it disappears very, very fast, fast as the messagebox window. This happens only if I have opened and closed the first child form. When I return to the main form after calling a child form with the lockscreen=.T., the commandbuttons are strange. Its do not go down when pressed! Is there somebody who knows the answer to this problem? Sorry for my english!
