Hi all, I've been plagued by this problem a rather long time. I googled around and couldn't find a cure. Maybe you'll be able to assist. Here goes: someone at work messed my file associations trying to show some cool "send to" trick. To access someone else's machine at work, what I usually do is press Win+R to launch the Run dialog, then I type the URI: \\some-pc\dir-on-pc, press ENTER and presto - I'm there. Since then, whenever I do that, instead of getting an explorer window pointing to the location I wanted to browse, all I get is the "open with" dialog (you know, the one you get when windows don't know which program is should launch to open your file). If I open a windows explorer window and type \\some-pc\dir-on-pc in the address bar, all is well, but that's an extra step. I can't spare the time and reinstall that machine, that's too much time consuming. It is is driving me crazy.
