Version: 1.10.1 (using 4.1.2 (KDE 4.1.2), Kubuntu packages)
OS: Linux (i686) release 2.6.27-7-generic
when I pressing PgDown or PgUp in the Composer, I waiting about 3 seconds, while cursor moving down line by line.
On every line it's drawing cursor and changing line number at status bar.
I have Core 2 Duo processor, 2 G RAM, Intel embedded video.
This sounds very strange, can you update to 4.1.3 and check if you can reproduce it? I'm unable to reproduce using current trunk. Thanks!
I'm able to reproduce it using svn trunk 885222.
Indeed, I can see the cursor going up (PgUp) or down (PgDown) line by line until the page changes.
