57100 - Dialog box spikes CPU usage to 100% until closed

Status: VERIFIED DUPLICATE of bug 56978

(SeaMonkey :: General, defect, P3)

Description

[Igor]

Note: I"ve noticed this error with a number of different dialog boxes, so
I think it applies to more than just the case below but this case should
reproduce the error.

1. Shutdown the link to the network so that the Internet is no longer available.
(I do this under redhat by shutting down the eth0 interface -- ifdown eth0)
2. Open a navigator window.
3. Enter a URL (I used www.wired.com) and hit return.

Results:  A dialog appears with the following message.

	"www.wired.com could not be found. Please check the name and try again"

					OK

Error:  When the dialog appears for some reason CPU usage spikes to near 100%.
	To check this run "top" in an xterm or your other favorite CPU usage
	monitoring program.  Under top mozilla-bin is using 90+% of the 		processor.
Clicking OK, closes the box and restores CPU usage back
	to normal levels.

Obviously a minor dialog box should not max out the CPU.  As noted at the
beginning I've noticed this with a number of different dialogs (e.g. I didn't
have the "Always use name and password" button clicked for an SMTP server in
Mail, this resulted in a message box telling me that I couldn't send my mail
successfully, which also spiked my CPU usage).

Using RedHat 7.0; kernel 2.2.16.22; Build 2000101708

marking dup of bug 56978, also filed today and about the same phenomena.
56978 "alert dialog consumes 100% cpu if network is down"
