Yes, you can execute a modal dialog without using exec(). >From http://www.webtoolkit.eu/wt/doc/reference/html/classWt_1_1WDialog.html: WDialog can be used as any other widget. In this case, the WDialog is simply instantiated as another widget. The dialog may be closed by calling accept(), reject() or done() (or connecting a signal to one of these methods). This will hide the dialog and emit the finished() signal, which you then can listen for to process the dialog result and delete the dialog. Unlike other widgets, a dialog does not need to be added to a parent widget, but is hidden by default. You must use the method show() or setHidden(true) to show the dialog. So, instead of exec(), use show(), and listen to the finished() signal instead of inspecting the result of exec(). This does mean that you cannot build your dialog on the stack, and for a complex dialog you will want to specialize WDialog to keep track of form fields. See for example FileEditDialog in TreeViewDragDrop.C (treeview-dragdrop example). In the mean-time we have been brainstorming about solutions to the original problem. One solution would be to not spawn a dedicated thread for each session, but instead make it so that a session is always handled by the same thread (by using a hash function on the session ID which hashes it on a thread from a thread pool). However, we currently do not see how this can be done in conjunction with our current asio design for wthttpd.
