I'm not a user of source control - guess why! Surely though you are trying to edit files and I would expect RoboHelp not to allow you to make changes until the topic is checked out to you. Otherwise you could be making a change to a file checked out to someone else.
See www.grainge.org for RoboHelp and Authoring tips
Of course. But there should be a way to open and edit files (with automatic checkout) from the Find/Replace dialog. Otherwise it's of no use at all under source control.
I'm not sure if you already figured this all out by now.
But I'm having the same problem with version control. And I just realized upon reading this thread, that I can do File > Version Control > Check Out All, and then find and replace.
Worked for me.
Ah ha, thanks!
