Application blocked in webclient

Hello
I post here because we encounter some problems with the web client. Our solution is based on Sample CRM.
Several times a day, when the user clicks that to perform any action, our solution is stuck with the text “loading” at the top right. This is totally random. To solve the problem, we need to refresh the page.
Is this normal behavior? Is there a solution ?
The problem is here since a long time ago.
We are in Servoy 6.
Thank you and sorry for my poor english!

without seeing an example its hard to know what is going on.
If it is loading then normally it means that a request to the server is ongoing, and because you can do a refresh it seems that there is really no request going on at all (else it would have blocked the refresh also)

clicking on another button doesn’t also have any effect?

Thank you for your answer. I know it’s hard without a precise example, sorry.
Yes that works fine when we click on another button.

Here’s what happens when our application crashes randomly in the WebClient :

So, when a user is blocked in the WebClient, this is the same symptoms than that I just mentionned : we can’t navigate between the sections anymore.

Do you think that could be a problem with our Internet (mini disconnections) ?

Its hard to see what goes wrong there without seeing more.
It looks to me that a tab change or something is just not allowed. The only thing that comes back is the menu (that left side) when i click on it
Nothing else.

Are there any errors in the log if you do that? When you click on a link and it won’t change?

It has something todo with the tab change that you do (you get exactly the same thing if you just open a new tab without closing and pasting the url of the first tab into the second one)
Try to see if you can make a case with that solution or a simpler version that also does this, so that we can look at it.
