Hi,

My app uses gecko as GUI for a c++-application. I manipulate the DOM 
through XPConnect in order to show some content (html). I also use some 
javascript functions in the html-code for image-changing and others. I 
now want to know, if i can synchronize the access to the DOM, so that js 
and c++ runtime don't interfere. Now sometimes the engine crashes 
(NetscapeDispatchWnd) when the access from c++-side is too fast (js 
hasn't completed its action before c++-access). I think i have to get 
control over the js-runtime.

Example: onMouseDown="imagechange();" 
onMouseUp="imagechange();sendIt(this.id);"

'sendIt' makes the connection to the application thread, which then 
evaluates the id and generates some new content (DOM). I thought, when 
sendIt is the last function, the js-function imagechange() has finished. 
Sometimes it hasn't, and the application thread tries to modify the DOM 
too, what causes a crash.

Can someone help me with this? Is there a synchronization method for this?

greetings
Timm
