XnView Software

Hi,
I just found out about XnView, and I think its the best viewer.

I recently tried the swf plug in, and I didn't like it, however I cant remove it

See before I installed it .swf extension were automatically opened in associated program. And now when I click them nothing happens, and I have to use F3.
I tired reinstalling xnview, and it didn't help. I tried playing with options, and everything seems all right, I marked open in associated program for other file types, but it doesn't do it.
please advise.

What program did they open in before? What you need to do is manually set them to open in that program. Go to a folder with a swf file in it, right click it and choose "open with", choose the prog they used to open in, and make sure to check the "always use this program" box.
