I have a form that has about 200 labels on it, to display various bits of data. The form background is green, and the labels have a white background, with an alpha value of 100, to give a semi-transparent look. However, when the form loads, it updates each label individually from the appearance of the previous screen, taking about 10 seconds, and similarly whenever I move another window infront of this form and away again.
This did not happen when the labels were opaque with alpha set at 255. Any ideas on why the refreshing is so slow? Thanks.
