Firefox loading icon never stops (dhtmlxtree)

Hi,



I am using dynamic loading in dhtmlxTree (via XML) and when I open a node in the tree, the loading icon in firefox starts, but never stops. Actual tree behavior is not affected, but I’m wondering if a socket is still open somewhere (via ajax presumably).



It could be a FF issue, but I wondered if there is anything special I should be doing in event handlers. I have registered onOpenStart, onOpenEnd and onClick handlers which all return true.



Have you seen this before?

Issue can be reconstructed in some situations ( it seems it based on server configuration and not constant )
Technically browser closes all connections after loading data through xmlHttpRequest, but still sometimes the icon still show that loading in progress.

>>I wondered if there is anything special I should be doing in event handlers.
The usage of built in events can’t prevent or interrupt data loading operation , this part of logic is isolated by browser. So any code in js events can’t cause effect on loading icon of browser.
