I search for X11 style middle mouse button. There is a TXMouse that seems to just overwrite the middle click, so for example it blocks opening links in browser with middle click. Is there a software that would not interfere with normal use and still use CTRL to paste it would be great.
I used to use this for my Evoluent mouse. It has "per application" settings:
I was a fervent user of TXMouse before, but for some reasons I didn't kept it when getting a Win7 work laptop... I can't recall if wasn't working or what, but for the middlemouse issue you describe my fix was to blacklist the browser and use an add-on that implements the select-paste functionality.
I just tried X-Mouse Button Control, and while it does provide the middle-click paste functionality I can't seem to find a way to get select-copy behaviour... Looks like the copy function they mention has to be bound to a mouse button (4th or 5th?).
So the one I've used since then was AutoClipX. I don't really like the UI and there are too many option IMHO, but it does provide a fairly good select (copy) & paste (middle-click) functionality. It's not perfect though (I don't think TXMouse was either) and one nice thing is it can play a sound on copy so you know when it didn't copy for some reason.
Like TXMouse, some application (Putty, KVIrc some browsers w/ addons) have the functionality bundled and it can be disabled by adding these apps in a blacklist.
