Why hasn't the ability to Right click Copy & Past been fixed? This was broken from the go start of ST8 and reported. Yes you can use your Ctrl key. but it's easier and faster the other way.
Strange that it hasn't been fixed yet. Did you log this with your VAR or GTAC?
Reviewing the associated PR notes on this issue, the issue has been fixed in ST9.
The PR notes also state that unfortunately the fix cannot be backported into ST8.
If you had submitted an IR/PR with GTAC/your Partner on this issue you should have received the CRR letter stating all this when the PR was fixed back in November 2015.
