>Hi,

>Just by chance we found out a problem when using GIFs, we do not know if it is a well known problem or not (a quick search in UT gave negative results). The problem is that thisform.refresh will make a GIF displayed on an image control visible, disregarding the actual value of the 'visible' property of it, even if you put the image control in a container and hide the container.
>
>For example, this will show 3 images, the first one with just the image control, the second one we overlap the image with a shape (this works as a workaround in this case) and the third one is an image control inside a container that we make invisible:

>Now after running this program if you click hide, all images are hidden, but as soon as you click the refresh button, which calls thisform.refresh(), the images 1 and 3 are shown again, although their visible property remains false, as shown in the checkboxes

>By the way, I do not know why the code generated by class browser does not work, I needed to change the code that is commented out and put it in the init as a quick workaround
