Version: 1.9.5 (using KDE 3.5.5, Gentoo) Compiler: gcc version 3.4.6 (Gentoo 3.4.6-r1, ssp-3.4.5-1.0, pie-8.7.9) OS: Linux (i686) release 2.6.18-gentoo-r6 The changed size of the preview window wasn't restored if I end the KDE session and start a new session. But if I exited KMail explicitly in a KDE session and stated a news KDE session the size of the preview windows was restored correctly.
Oops, forgot to close this bug - "save sassion" is the answer
