Hi, I agree with esvignolo, he was trying to update bgracontrols from external sources.
I know how it works and now he knows too. But for someone that never used it it can give you the impression that is not working.
A suggestion can be, if you already have that version installed, say
bgracontrols 4 installed, and you choose bgracontrols 4 to install again, and at the same time there's an external version available say bgracontrols 4.x (external update), when you click on install a prompt that says 'you want to re-install the same version or update to the external new version?, two buttons [Re-install bgracontrols 4] or [Update to bgracontrols 4.x]'
Or some better approach, I don't know
Thanks again for this excelent tool.
