Browser shuts down with any "browse" button
I mentioned an issue once before where if I tried to import a bookmark file the browser would close the second I hit "browse", now it appears that this issue is not limited to bookmark import, any site where I require browsing for a file (e.g uploading photo's to facebook or any similar situation) causes the browser to close the instant I click the browse button.
I have no idea what might be causing it but it's stopping me switching over permanently to Vivaldi, I am on the latest snapshot 1.5.676.6 (Official Build) (32-bit). Any ideas? it's driving me mad.
