Version: 1.8 (using KDE 3.4.0, compiled sources) Compiler: gcc version 3.4.3 OS: Linux (i686) release 2.6.10-ARCH When you begin typing an address in the To: field, you get the expected dropdown box of text completion possibilities. However, at that point you seemingly can only pick the one you want with the mouse. Arrow keys fail to be recognized.
I confirm this bug. This bug is rather random. Sometimes the arrow keys work and sometimes they dont.
Tried to reproduce with KMail 1.9.10 and SVN trunk r860760. Couldn't reproduce that behaviour. The problem seems to have been dealt with meanwhile.
I can't reproduce this bug either. It has most likely been fixed in the meantime.
