Texmaker and TeXstudio ⇒ Internal PDF Viewer doesn't jump to right Page

[hinsen]

First of all: Hi everyone!

I ve got a problem with the internal pdf-viewer. Since yesterday it does not jump to the page, where my cursor is.
That is a bit annoying with a long document... I fiddled in the options, but i cant work out, how to get this working again.

Any suggestions?

Thanks
