CSV_MessageBox function does not work correctly when iTimeout value entered is greater than 16. When the value entered is greater than 16, the message box will display but never time out. In addition, when the iTimeout value is greater than 32, the message box will not display on the screen at all. Is there a timeout limitation when using CSV_MessageBox?

The timeout in CSV_MessageBox is implemented using a timer control that has the timeout specified as a VB integer (signed 16 bit type). As a result, the maximum value for timeout that CSV_MessageBox can use is 16 seconds.
