it might be that whne the form close someone wrote some code that is process and possible even put somthing like thisform.lockscreen=.t. etc. you can put a thisform.hide() as the first line in the process that occurs during close (in Queryunload event or whatever you use) Arnon > >I've recently inherited a project from another developer. Today I was running it for the first time and noticed that each time a messagebox (or a form) pops up, that when it closes the underlying form has a white spot for a second or two where the dialog box (or other form) used to be. The projects I've done in the past don't seem to have this problem. Does anyone have a clue? Thanks.
