Christof,
I for the first time in a long time put a spinner on a form. They used to accelerate the longer you held the mouse down. VFP5 SP3 doesn't behave that way though and it's basically too slow to use IMHO. I might try adding a MOUSE command in there to move the mouse pointer 1 pixel and see if that helps.
>This is a general issue in VFP, no only with DoEvents(). For example, if you put a spinner on a form and click the up button, increasing the value is relatively slow. If you slightly move the mouse on the button, it suddenly speeds up.
