There seems to be a glitch with the Preview feature (so far only observed in HTML Source preview; didn't try anything else)

Preview seems to generate a Warning message ("Tag ... missing") which then causes the Messages pane to be activated.

I have it in the same group as the Translation Results which I have to switch back to if I want to see the TM results.

When I close the Messages pane then it will pop up anyway on moving to another segment.

Odd is that the complaint is about a missing tag in the target even when I want to preview the source.

If there are not many errors I can insert the missing tags which resolves the issue. Unfortunately there often a too many in a pretranslated doc to do this quickly.

Is there a way to deactivate the Message pane during translation? That would be nice for other panes as well (eg. the Termbase View, for which I don't have any use)
