    I don't know if this is a more bug...

    In some moments, when I use the scroll bar up or down, the text of TexMakerX takes a strange way.
    Take a look this:

    To solve this I run Ctrl+A (select all text) and click on the text.
    Take a look again:

    This happens often.

    Thanks for your help!

      I got this response: (although I wrote him that you had KDE 4.2.0 ,qt.4.5rc1 like in your last thread)
      >I have updated to Qt 4.5 and I am still unable to reproduce the bug. I guess it is either a local issue or a bug

      So you were perhaps right with suspecting KDE/QT.

      Uihh, that's bad.
      There was a bug in the QCodeEdit-library where exactly this happened (but on Windows only), however it should have been fixed already (in the version included in the TexMakerX release).

      Which version of TexMakerX do you use? (release or svn-revision, the number in the about-dialog is currently not really useful)

      Anyways, I reported it now to the qce author.

        Hi Benito,

        Bad bug! ;)

        I was suspicious of KDE4.

        I installed the svn version of TexMakerX on KDE 4.2.1, QT 4.5.0, Gentoo 2008 (64 bits).

        Thanks Benito,
