[OpenLayers-Users] Bug in LoadingPanel + testcase

[manel.clos at ajgirona.cat]

Hi Bart,

As explained in my previous post, I tested using the example at:

http://dev.openlayers.org/addins/loadingPanel/trunk/examples/loadingpanel.html

If you remove usage of PanZoomBar and MouseToolbar, and use Navigation, it will show the bug. Everything else is as in the example.

So, yes, LoadingPanel is the first control added.

Hi Manel,

what is the sequence in which you add the controls? Are you adding the
LoadingPanel as the first control before adding the Navigation control?
