I have forgotten a little detail, the "Up" at the end, check again please. Otherwise you can easily nuke several apps in a row if you are holding down too long. This one closes after releasing F1, not while holding down.
Finally, if you are still having problems Action Canceled with VirtualDub's help file, right-click on it in Windows Explorer and choose Unblock. The reason for this problem is that the KB896358 security update from Microsoft prevents HTML help files from working if they are located on a network share or have the Internet Explorer "downloaded from the Internet" tag (which shouldn't be getting applied to files from a .zip archive, but somehow is for some users). 1.7.0 will display a warning and offer to strip the Zone.Identifier stream, but you still need to do this manually for 1.6.17. You will have problems regardless if you place VirtualDub on a network share, so move the .chm file to a local drive and open it locally in that case.
