KMail 4.14.3 on KDE 4.14.3:

I am reading email in the folder KDE for example and delete after read. And 99% of deleting after one or to deleted emails on the third one a folder close. I need to choose another one and than go back for try to delete again.
I don't know if is a bug but the same problem I had with KMail two years ago when I had enough and switched to GNOME 3 and Evolution. Looks like that is time to change an email client.

Thank you.

Can you make an example of the undesired behavior that occurs?
