Thanks again for the suggestions. I actually didn't know about the flags before now. I checked as many I could on that page before it crashed and they were all at their defaults. No extensions are being used.

Still crashing. Any more suggestions (please)?

Hi, I've just upgraded to Windows 10 and find that nearly on every tab I open a couple of seconds after the content of the page appears I get the screen "Page crashed". This evens happens when a tab is opened to show the About Opera info - hence it seems a problem with the browser rather than its compatibility with web pages. I have already tried uninstalling and reinstalling. Any ideas of what is causing this and how to fix it?
Thanks,
Nigel.
