I find some issues about VFP running on Vista. Maybe you have found others. Please post them, if any.

1) The height of our spinners (in our class libraries) is at 20 pixels and that for our combobox is 19. They have been working fine with our standard font Tamaho point 8 for a very very long time. Once our applications are run on Vista, I find that 24-pixel high is necessary for a spinner. Otherwise visual distortion will be seen on the spinner buttons. Similar visual problem is found for comboboxes less than 23-pixel high. Changing the height of a spinner or combobox is not difficult. The problem is fine tuning the positions of the controls around the spinner and combobox is necessary. It could cost numerous hours of work for tons of forms in different VFP applications.

2) The images on toolbar buttons are not properly vertically centred at the middle of a toolbar. Excess while space is shown at the bottom of a horizontal toolbar. The standard toolbar is an example exhibiting this issue.
