Hi there.
Guess what happens when you move from skinning to scripting? Things crash!

Anyways, I'm using that old dialog Choli posted some time ago, but my script crashes messenger if I close the original window, open the file dialog, and open a new window after choosing the file (or just canceling it). I mean, this:

jscript code:

//variables declared way back
function OnBkdWndEvent_CtrlClicked(Wnd, ControlId) {
    BkdWnd = Wnd;
    if (ControlId == "BkdWnd_MAINBKD") {
        Bkd_ConvoWnd = BkdWnd.GetControlText("BkdWnd_CONVOBKD");
        if (DebugInfo == true) {
            Debug.Trace("\"" + Bkd_ConvoWnd + "\"" + " saved to Bkd_ConvoWnd variable");
        }
        >>>BkdWnd.Close(2);<<<
        if (DebugClick == true) {
            Debug.Trace("BkdWnd_MAINBKD clicked");
        }
        if (DebugInfo == true) {
            Debug.Trace("Closing BkdWnd and opening File Dialog");
        }

            filter = "Image Files (*.png)|*.png|Image files (*.jpg)|*.jpg||";
            s_filter = Interop.Allocate(2 * (filter.length + 1));
            WriteMultiStringW(s_filter, filter);
            WriteDWORD(12, s_filter.DataPtr); // lpstrFilter

        else {

Take a look in my beta script... I use the same function and as far as I can tell it works in that situation.

Rather than using GetOpenFileName, I return the path from the function the comdlg is defined in.

I'll try that, thanks

I'm trying it now, I'll send it in a min
