Description Chris Pimlott 2008-04-18 23:56:35 UTC 
Version:           1.9.6 (using KDE 3.5.8)
Installed from:    Ubuntu Packages

The message preview pane content scrolls by different amount depending on what method you use to navigate:

* PgDn/PgUp
* Alt-PgDn/Alt-PgUp
* Spacebar
* Clicking in the scrollbar area below/above the bar

Screenshot included to show difference.  In this example, PgDn scrolls by the least amount, followed by Alt-PgDn and spacebar, which scroll the same amount, and then scrolling by clicking the scrollbar, which scrolls the most.

It is unclear why they should scroll by different amounts.  The behavior should be consistent across all methods.

The results are similarly inconsistent for paging the message pane when viewing a message in its own window as well.

Confirmed this bug still present in KDE 4.2.2. Scrolling in an message window with the different methods scrolls by different amounts, although I get Space as least, then Alt-PgDn, then PgDn as the most.

Confirmed in trunk too.

Thank you for taking the time to file a bug report.

KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2.

We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
