Haha I've had a very similar bug when trying to modify the game cards with my script, because a single card is reused it can be quite tricky to iron out all the bugs.

I'll see what I can reproduce myself.

Well, as long as there are the classic installers without the same problem...

Galaxy itself will auto-update when you first run it, so they don't really have to keep it up to date. Besides, didn't Destro already confirm that they plan to make the Galaxy installer a small stub eventually (to which you will need to be online for Galaxy to install or the installation will continue without installing Galaxy) and are temporally including Galaxy until that is ready?

Not maybe with every new version, but I'd figure having a very old (months, even years old) Galaxy installer might be a security problem, until it gets updated (e.g. if there was malware targetting specificically the old versions, even blocking them from auto-updating). Or the old client doesn't even launch properly due to some Windows update or whatever...

Also, from my experience these auto-update thingies tend to get broken at some point, ie. you can't update from any old version to the newest version. I'm in that situation with e.g. TOR browser now. It has a button which should update it to the latest version.... but after not having used it for a few months, that update just gives me an error and tells me I should redownload the installer and install it manually.

Would you feel comfortable installing a Galaxy client which was, say, five years old, and just hoping it will successfully auto-update to the latest version?

I didn't say they should never have to update, of course they may want to update it when a significant version releases. They simply don't have to do It for every minor update.

Besides, again if they follow through with making Galaxy an stub installer as they have already said they plan to do then this really becomes irrelevant...

I can confirm that what you report is the case.
I'm not sure entirely how you load the different installers but from what I can tell you replace the actual URLs in the data. Now when you open and close the window this is not reverted (despite the Classic or Galaxy installer setting being reverted), so all you need is to make sure the Galaxy URLs are loaded when the setChosenID function on the GogProductChooserController is called.

I can't find any way to reproduce what the OP reported, and can't really see a way for it to happen as as far as I can tell the boolean controlling the change of titles should always be reset when the game card is open again.. unless something external (a script) changed something.

I love how the good people that work at GOG resolve this issue, but still their work and company are slandered with this title of the topic subject and negativity of the forum. No respect for the hard work they do to make everyone happy.

Well, customers let be, If you work with shit, you'll get dirty.

The people who brought GOG to the position it is now you mean?
Correction, was half a year ago.

Is Galaxy better than chlamydia? Probably. But still....

It's hilarious that the galaxy bashers have literally banned together as a bunch of bullies and are forcing their views on the populace.

Galaxy -- it's better than Donald Trump!
