So weird issue I've been having forever. If I click a link in outlook or some other software to launch my default browser (latest opera stable) it takes 1-2 minutes to load and remains very very slow. I have to quit, wait for all of the opera processes to die and then manually launch it. Paste in the link and it works fine. I learned that I can create a hotkey to launch the actual opera app first (not the launcher) and then it works fine when I click on links. I don't experience this issue with Chrome.. it's only opera. Forgot to mention I have the shortcut manager (executor) launching opera in Vista Run as mode. Otherwise, I get the same slow behavior launching. The shortcut manager has to launch the app, not launcher or its back to slow.
I"m running the latest Windows 10 with all the updates from Microsoft as of today. Issue has been going on for almost a year.
Note that I've totally 100% removed my opera %appdata% files more than a few times and started from scratch. So having me delete session files is not the answer here. They may be "storing" whatever is slowing me down, but don't explain why they are going south in the first place.
