Hi, Lyle.

Thanks for your tip, but I am afraid it didn't work.

The point is that I have the following code, in my custom dialog box:

def execute
	t = Thread.new { regressao }
def regressao
	while @regressor.progress > 0 do
		@regressor.progress -= 1
		sleep 0.05
	handle(self, FXSEL(SEL_COMMAND, FXDialogBox::ID_ACCEPT), nil)

Here, I create a thread just before calling super, to implement a
"regress" bar, shown in the dialog. I want the user to be prompted for
as long as n seconds (here, 5 seconds) and, if she didn't atend to the
dialog, the dialog takes a default action (in this case, the ID_ACCEPT).
The thread works just fine, with the regress bar showing pretty well,

Well, inserting the line handle(...) from your tip just made the dialog
to freeze, with cpu usage hitting 100%. Program needs to be killed.

I have tried to move the thread "regressao" to the main window (the
parent window for the dialog), but it just doesn't get called.

So, any idea on how to solve this problem?

Thanks a lot,
