Just to add another data point, clipboard copy of straight text (url links, usernames, passwords, etc) seems to have gotten less reliable in 6.2.x ->. Previously, you could reliably expect a copy of short, plain text at either end would automatically appear at the other end without using the menu Get/Set actions. Now I almost always have to use the Get/Set menu action.
We are planning to re-write the code responsible for clipboard sync for ID connections in the near future anyway. Hope that will fix these issues.
Unrelated but another issue: Please promote the 'Ctrl-Alt-Del' menu item back to the main bar as it was in 5.x. It is one of the most used functions and it's a bit silly to have to now dive into a menu to get at it.
That makes sense. We'll probably do that in the next update.
We will allocate more time and resources on improving how the clipboard copying work then.
Regarding the 6.3 upgrade - I have responded to you via tickets yesterday. The reason could be that you were using a custom installer for upgrade that was set to overwrite existing Host settings during remote upgrade.
We haven't received any other reports about issues with upgrading, although the new version has been around for almost a week now.
Don't hesitate to ask me if you have other questions.
