Ok, just to make sure that there are no more issues, here is a 126.96.36.199 build for you to test before we officially publish it. We did quick in-house testing and didn't find problems, but your feedback is welcome:
UPD: The new version has been published. Download from the download page.
Note: If you have issues updating Viewer from 188.8.131.52 to 184.108.40.206 (e.g. error messages), then manually uninstall the Viewer first using the Windows Control Panel and delete the file config_4.xml that you can find in C:\Users\username\AppData\Roaming\Remote Utilities Files\. Then install 220.127.116.11.
Also, Offline/Online problem is no more both on 6.5.x.x and 18.104.22.168.
Looking forward to your reply.
P.S. It is also recommended that you upgrade your RU Server after you update the Viewer, although Viewer 22.214.171.124 must work with Server 2.5 without a problem.
This is temporary. We made some changes to the public server so that this online/offline bug no longer appears in version 6.5 (so it was a retrospective fix). To eliminate the bug in version 6.6.x.x we'll release an update in a couple of hours (126.96.36.199).
So please do not downgrade, just wait until we put a new version on the site. That should fix the problem.
Thank you for the report. Our engineers are currently looking into the issue. Looks like this could have something to do with encoding issues in the IDE environment that we use. Anyway, we will do our best to fix the problem as soon as possible and update the installers in the download section.
We'll also change the version number so that you can distinguish the updated version from the current one.
