When I try to copy/paste a url it doesnt show me the option paste, but only copy. That is only with URL, I have the option paste when I work with text files, anyone knows why?!!

Because you didn't properly copy the source perhaps? Give me an example of something you can't copy/past to where.

It isnt that. If I write THIS with wordpad or anything else, then I open Explorer, I cant paste it here. But I can copy/paste in the text file I wrote outside internet. It seems internet erase what I copy. This occured 1 week ago, before all worked fine

Go to majorgeeks.com and ask the resident geeks, they are very helpful and fast to respond.

If you were using Word, I would say "that's a new feature." It is documented that unless you have Word open when you execute the "cut/copy" feature, it often won't let you paste.

Maybe new versions of WordPad do the same thing.

Several programs clears the Clipboard when initiated for some reason. I once recently copied something shut down the source and then started the target program, which meant I couldn't paste it. Same thing as ML said, but that more programs than Word does it.
