Cannot reproduce, works just fine here.

Can you reproduce it on a different system?

Vidual Studio Just-In-Time Debugger only pops up when the "Clear quickconnect history" check box is checked. If unchecked, everything works as expected.

Hope this will help to track down the issue.

You should have mentioned that you have hidden the quickconnect bar.

Will be fixed in the next version.

[fzuser]

Sorry, my bad. I'll recall it next time.
