Jeannot - I am pretty sure @Greg_O_Lone and the team can make something happen here. The “curtain” effect isn’t the most visually appealing way to show that data is being loaded. Sometimes the curtain will hang there indefinitely and like Brock said, the curtain might also appear at the top of the WebListbox. Greg is obviously a very talented developer and I’m sure he can either come up with a refined design for this and/or leverage additional functionality of the underlying tools that drive WebListbox. Even better, expose more customization options for Xojo developers to customize these behaviours.
I really do appreciate how much work it must take for the Xojo team to deliver on all of these feature requests from the community. I hope Greg knows, even through the noise, that many of us are impressed by what Web 2.0 is currently delivering in terms of features and functionality. The curtain effect is not a “show-stopping bug” but it’s one of those things that could hopefully be addressed soon because that strange effect will almost certainly confound some of our users.
