Browser, not engine. Reassigning to XP Toolkit/Widgets for further triage - not sure if that is the appropriate component, either. Confirming with Mozilla 2001-12-19-xx on Linux. CPU is pinned at 100% on prompt(), alert(), and confirm(). COMPARISONS I should note that on the same Linux box, NN4.7 also uses 100% CPU for prompt() and confirm(). But not alert(), which spikes at 100% but then comes down. Mozilla 2001-02-19-xx on my WinNT box uses spikes at 30% CPU on these, and then goes down to 1%. So this may be Linux-specific -
Sorry, that was 2001-02-19-xx on Linux ...
