Hi,

Please try to update to the latest build and see if it fixes the problem for you. We have fixed something similar so it might have already been fixed. The latest build should be free for you.

If the latest build still does not fix the problem, we will need you to isolate the problem into a test page and post the test page (along with steps). Once we have that we will run it here and see if we can reproduce the problem. Usually as soon as we can reproduce the problem, we will be able to resolve it.

Thanks!

Hi,

You are very welcome. An Url probably won't be enough for us for this case since this is a server side error, thus we need to debug the server side code. In any case, please let us know if the new version fixes the problem for you.

Thanks!

Hi,

As already mentioned in our previous reply, please create a test page to reproduce the problem. We will need such a page in order to investigate further.

Thanks!

It is very hard to reproduce the problem in the proposed way !!! - I try to follow up the response life cycle and I notice that the only Diff is some unload proccess came up. The crash happens immediately after the page_unload end ...
I keep trying to debug...

Hi,

No. We have not been able to reproduce the problem yet. Please try to isolate the problem into a test project. Usually as soon as we can reproduce it, we will be able to fix it or provide a workaround to you.

Thanks!
