I am creating a BMP but if you look at the attachment uploaded the Windows dialogue box also is included in the BMP - it doesn't happen on other versions of Windows but this is a brand new machine and the first time I have used Windows 10

Is there a Windows or VFP setting to stop the dialogue box being included in the BMP?

The attachment uploaded is a JPG copy of the BMP file as UT does not allow BMP files to upload
