>To get a more graphical, attractive look on a form, I've changed over buttons to images. An odd thing I noticed is that quick, successive clicks on a button are interpreted as single clicks in rapid succession. But the same clicks on the image are interpreted as double-clicks. So it would seem the double-click threshold is different for one control vs. the other. I'm assuming I can alter this with the _DBLCLICK sys var, but I just found it kind of odd. Not so much a question as an observation, but if anyone knows the reason, I'd be curious.

As a side-note here, don't forget that the windows OS has a setting for how long it takes for a double-click to happen - it's in the control panel / mouse settings.
