Description Stefan Lienesch 2006-11-27 15:05:55 UTC

Version:           0.5.5 (using KDE KDE 3.5.5)
Installed from:    Debian testing/unstable Packages
OS:                Linux

The automatic page switching in presentation mode works all right, even the advance time can be set correctly.

But after first time using a key/mousebutton to switch the pages manually, the automatic mode does not work any longer. The advane time is extremly short and irregular.

Comment 1 Albert Astals Cid 2006-11-27 20:20:34 UTC

SVN commit 608521 by aacid:

Using a singleshot timer to start the auto page change is bad because if the user changes the page manually you get more than one timer active at once and then next pages change in what seems a random time.
