12.16/win 8.1, 64bit, lose ability to enter text (aside from space and backspace) in browser windows
My browser has started acting strangely. I can't enter text in windows, search bars, etc.. aside from space and backspace. I'm using a different browser to type this. If I remove/reinstall, I have functionality until the next boot, then I can't type again. Very perplexing. Ive tried removing all private data in case it's some kind of cached setting and completely deleting the install folder, no success. I really really REALLY don't want to switch to a different browser, but I'm tired of uninstalling/reinstalling. Any assistance would be appreciated (aside from telling me to upgrade to the newest version, I'm on this one for a reason).
Perhaps try downgrading to 12.14, or an earlier version. It's possible a bug was introduced in the latest patch that's causing your trouble. It's also possible some other program on your computer is causing interference (more likely this, but try downgrading first).
What OS, and are you installing Opera for multiple user accounts?
Are you using any add-ons/extensions with Opera? If so, try either shutting them down or removing them.
Also, when you reinstall, have you tried installing into a different-named folder than the earlier installations were put into (eg, not "*\opera" but instead something like *\opera1216)? When Opera is installed into a folder, it immediately looks for left-behind files from earlier installations in that folder and auto-imports them, if any are present (along with any file corruption they may contain). Even if you "delete the install folder" but have separate user accounts, their similar-named user folders (located under AppData or ApplicationData) will remain to possibly corrupt a new install if made into that same previous folder name.
