@Alphageek Hi. Sorry to hear you’ve been experiencing this issue - it sounds the same as some of us have been having problems with. See the thread here (see point [3] in original post and the follow-up for my original complaint).
I tried a few tweaks but could not fix this and, since it was a deal-breaker in terms of workflow, have had to downgrade to v7… which works perfectly again. Several others on here have done the same.
It sounds as though the version (8.0.3283.0) from a few days back does not yet solve this issue. There’s a new version out today (8.0.3318.0) which you might try if you are persevering with v8. However, I can’t see anything made explicit in the list of fixes that would suggest it cracks this particular nut… 
Whether anyone at eM Client is looking at this, I don’t know, but thanks for adding your voice to the chorus of disapproval.
