I have a strange problem where if I try to show a chm help file my application locks up.
The application also hangs if I try to open a web page using process.start(url)
It also hangs if I try to show an OpenFileDialog.
This only happens when the application is installed on another machine (its ok on the dev machine)
I created another basic test application with the same functionality and it works fine.
I've tried help.showhelp(path to help file) and process.start(path to help file).
Also if I use process.start(url) then this also locks the application.
Double clicking on the chm file opens it fine so the chm file seems to be ok. I can also open it by running a batch file, but this is a bit messy. Also, this doesn't help with starting a url.
Anyone got any ideas of what could be wrong?
