Hi Jean-Marie,
Thanks for reporting this issue. We were able to recreate the issue and are submitting it as a bug to our development team.
In the short-term you could use one of the following workarounds:
Assuming you are using a style sheet just add the following:
.olControlZoomPanel {
display: none;
}
If you do not have an external style sheet you can add the following inline style tag to your HTML page. It’s best to put this within the head section of the page.
<style type="text/css">
.olControlZoomPanel {
display: none;
}
</style>
The CSS markup shown here will not affect the standard desktop pan/zoom controls, so you will want to continue using the proper method to disable those.
