Yes you are right. I just have a desktop launcher that runs the last executable, in my case: /home/steve/Gambas/HelpBrowser/HelpBrowser.gambas
You could run the Packager and include the .csv and .png files and it should work anywhere.
However, I'm still not sure if I'm wasting my time with the Control Locator. Its a lot of work editing screen-shots, adding a red blob, saving the png and adding details to the csv file. I don't use Gambas enough to be able to remember what all the Control Icons mean, or even where they are, so that was my incentive for trying this idea.
I'd probably be happier with a drop-down list of Controls directly in the IDE, rather than clusters of icons with vague tab titles, as it is at the moment.
